Read below for more details on what’s included in the free diagnostic check. There are many reasons why the check engine light in your vehicle comes on.

Some of the most common reasons for your check engine light to appear include problems with: If your check engine light comes on, be sure to take care of it as soon as possible.

Let the team at Joe Machens Hyundai help. If you’re having check engine light issues and you’re in Columbia or nearby Jefferson City, schedule a free diagnostic test at our dealership.

Oxygen sensors are a common cause of check engine lights. Oxygen sensors are used to make sure your vehicle is burning the correct amount of fuel and running at peak performance.

Over time, the O2 sensor can get covered in oil ash, which reduces its ability to monitor the fuel and oxygen mix in the engine. It costs around $200 to fix.

If the gas cap is loose or damaged, it can disrupt your vehicle’s emissions systems, as fuel vapors may leak out of the gas tank, leading to a decrease in vehicle efficiency. You’ll need to tighten up a loose gas cap or replace a damaged one.

By finding out and fixing the issue, you can save money on gas in the long run. Catalytic converters reduce emissions of your vehicle by converting carbon monoxide and other dangerous gases into harmless compounds.

However, they can have issues. Unfortunately, this can be an expensive issue, costing around $2,000 to fix.

It’s important to regularly service your car’s air filter, so you don’t risk damage to the vehicle’s mass airflow sensor. If you don’t replace the air filter, the air-flow sensor can malfunction, and provide incorrect information.

That’s why you need to replace your car’s air filter at least once a year. If there’s a problem with the mass airflow sensor, fixing it can be on the more expansive side.

If there’s an issue with a spark plug, this can cause the engine warning light to turn on. They’re pretty cheap and easy to replace.

If you take it to a shop to have them replaced, it can cost you a little more money. When your check engine light comes on, it’s important to get it checked right away.

But, you won’t know what the issue with your vehicle is until you have it checked. It’s important not to panic.

Don’t go trying to replace parts without first diagnosing your issue. This is a waste of time and money.

You can often do it for free. Here’s where you can get a free check engine light test.

You can visit your local store to get free engine code scanning on most OBD-II vehicles. Advance Auto Parts says it cannot guarantee the problem can be resolved during the visit, but that it’s happy to refer you to one of its local professional technicians if a more comprehensive diagnosis is needed.

AutoZone has more than 5,700 locations in the United States, and all of them offer the Free Fix Finder Service during business hours. AutoZone calls its Fix Finder Service, “The most complete, free warning light report backed by the most robust database of technician solutions.”.

The test often takes less than a minute once the reader is plugged in, so it’s a pretty quick process. Then, you’ll get an easy-to-understand report that’s informed by millions of technician-verified fixes.

The report details recommended solutions and suggests parts needed for repair. Staff members can help you to find the right part, and also recommend a local technician if you require additional help with the fix.

Head to your local O’Reilly Auto Parts store and it will scan your codes for you and provide a list of possible fixes. It says that some codes may call for further diagnosis, and when that occurs, they will be happy to refer you to a professional technician.

Visit your local store for its Free Engine Light Code Pull Service Package. There are a few other ways that you can have your engine light checked for free.

Amazon is a good place to buy this tool because it offers them at pretty low prices. This Universal OBD2 Scanner Car Code Reader, this Wireless Bluetooth OBD2 Scanner & Fault Code Reader and this WiFi Car Code Reader Check Engine Light Diagnostic Scan Tool are only around $20 each.

You may be able to get your light checked free of charge by visiting a local mechanic. You’ll have more chance of this if you already have a local mechanic that you visit for your usual car needs.

And, they’ll be able to tell you what’s going on with your vehicle. If you have a mechanic you’ve used when your car has needed repairs or maintenance, get in touch and ask if they offer a free check engine light service.

This can be a good option if you have a mechanic that you trust because they can help you a lot with getting your car back to running properly. I would recommend getting a free scan at your local auto parts store, like AutoZone or Pep Boy Auto Parts.

Of course, there are other options like buying your own OBD-II scanner and checking the light yourself or taking the car to your regular mechanic. Whatever option you choose, make sure you have your car engine light checked as soon as it comes on.

Does your gas cap not quite tighten (click, click, click) like it use to. Do you smell gas.

Is your check engine light on or flashing. This page discusses why a check engine light comes on or is flashing.

The engine warning light indicates a problem that needs prompt attention. A car diagnostic test machine communicates with your car’s OBD (on board diagnostics) module.

Our car diagnostic test equipment shows us the error code number which saves time in identifying the exact cause of the problem. We provide free car diagnostic test services when you hire us to do the required repairs.

If your check engine light is on your car needs some type of work, so why not choose us to go ahead and fix it. Our hourly rates are far less than the big name repair shops or dealerships.

We can give you a free estimate for car repair service before we do any repairs. What does the check engine light mean.

A check engine light usually means that we can pull an error code with a car diagnostic test. The electronic car diagnostic test saves many hours otherwise spent to troubleshoot engine problems.

The sudden appearance of a check engine light means your car’s computer has detected a problem that needs prompt attention. The problem relates to the general operation of your engine.

Why is my check engine light blinking or flashing. When the check engine light is blinking it usually means an engine misfire.

Possible causes are a blown head gasket, valves stuck open, no detonation on a cylinder or other severe problems. In many cases driving your car in this condition can cause irreparable harm to your engine.

Simply clearing your check engine light does not resolve any problems. Even if you do reset the warning light, it will quickly reappear because there is a problem.

In some cases the light will go away on its own after the repair is handled. In other cases there may be a procedure using your key and ignition switch.

When something goes wrong with your car, a DTC- or diagnostic trouble code- is sent to the car’s computer. It is almost like sending an S.O.S.

is just a sign that someone’s in trouble. Unless the S.O.S.

A DTC, on the other hand, tells your car that something in a specific part of the car is wrong. When your car is hooked to a diagnostic testing machine, that code translates that information to the machine.

The test should be comprehensive, meaning it tests all vehicle systems including the car’s airflow, fuel injection, transmission and brakes, exhaust system, ignition performance, and sometimes more. Code in hand, the mechanic then takes a look at that specific part of the car.

At this point, you will also get pricing on getting said trouble fixed.

The total time it takes is typically just a few minutes on the machine. It should not really take more than an hour for the mechanic to take a look at any problem areas.

For a comprehensive car diagnostic solution, Car Scanner ELM OBD2 stands out as a top choice. Renowned as one of the most versatile vehicle diagnostic tools, it is compatible with an extensive range of vehicles.

Upon connection, users gain access to real-time data streams from their vehicle’s sensors. The app can pinpoint engine fault codes and facilitate their removal.

While a majority of Car Scanner’s features are available at no cost, users will encounter ads. Opting for a subscription eliminates these ads and unlocks advanced functionalities, including simultaneous display of multiple live data streams.

Given the nominal difference in pricing, a lifetime subscription offers unparalleled value, making it the recommended choice for users.

The dreaded Check Engine Light… no Phoenix driver wants to see that pop up on their console. When you see it, it could mean anything from your vehicle being overdue for an oil change to a loose hose or a broken seal.

If one orange light strikes fear in your heart, you’d better have Chelsee’s AC & Brake Emporeum stored in your phone so you can call us the moment it comes on.

Looking for only the best 5-Star auto repair Phoenix. Call us now and get a FREE check-up.

Even if you don’t get the visible warning from your car that something is wrong, sometimes you just know. It takes a little longer to start up today than it did yesterday… There’s a weird noise coming from under the hood… The ride isn’t as smooth as it’s always been… Whatever little sign you have noticed that’s making it a little harder to trust your vehicle these days, Chelsee’s has the solution: auto diagnostics Phoenix can trust.

With so many moving parts, there are countless things that can go wrong with an automobile. Finding the exact problem is part skill and part luck sometimes, if we’re honest.

GM implemented an assembly line diagnostic link in vehicles built as early as 1980, and in addition to that company’s constant improvements and updates, other auto makers realized that on-board diagnostics as well as computer diagnostics provided by private auto care centers were a really good idea and began incorporating them into their vehicles as well.

Vehicles manufactured since 1996 are fully compatible with our testing equipment, and many makes and models from previous years can be tested as well. All you have to do is contact us to find out if your automobile can be tested by our modern equipment.

Regardless of the part of your car that is giving you trouble, you can bring it to Chelsee’s AC & Brake Emporeum LLC for auto diagnostics. Our testing equipment can help us identify the services and repairs that need to be performed.

We believe that finding the problem is part of our job so at Chelsee’s, you’ll always receive two things: Auto diagnostics are a tool we use to locate the problem.

We could easily go about it the old way – keeping your car for days, inspecting every system painstakingly by hand. This method works, but it is slow and sometimes inaccurate.

There are literally thousands of things that can be wrong with an automobile, from the engine to the suspension, so even something simple can be overlooked in our fervent search for an issue that has caused your vehicle to perform less than optimally. With diagnostic testing, we can go straight to the source of the problem in many cases and make the repair while you wait.

Customers and our own technicians love that, and the best part is that it’s always a complimentary service.

Therefore, we put our reputation on the line each and every day, giving customers free estimates that they can take home and think about or compare with information they have received from another mechanic. We want customers to choose Chelsee’s because they believe we’re the best, not because they don’t have another option.

Whether we see the problem right away or have to employ diagnostic testing to be sure, our technicians will provide Phoenix drivers with a free estimate, in writing if needed, so they can review our results and do their own research. We certainly don’t mind being compared to other Phoenix auto care centers because we know our services are high quality and 100% worth the money.

Once you have had FREE diagnostics performed and received your FREE estimate for services, you’ll then have the freedom to choose Chelsee’s AC & Brake Emporeum or any other Phoenix auto garage. That’s how we guarantee excellent customer service, from diagnostics to full-scale auto repair.

We can also keep up with your services so that you don’t have to remember when it’s time for the tires to be rotated or for an air conditioner service. We’re highly experienced with brakes, engines, transmissions, shocks, and suspensions, and we’ll go over your car in a thorough manner so that we can find any problems.

The Chelsee’s team is unique because we don’t rely on just one method of diagnosing automotive problems. Instead, we use a combination of the latest technology and hands-on inspection to find the issue and double check that a) our diagnosis is correct and b) there are no other problems, either related or unrelated.

Proper knowledge of how on-board diagnostics and our own testing equipment is paramount for achieving the correct diagnosis for your vehicle. No matter what make or model, we have the equipment and information to do the testing correctly and read the results accurately.

The role of computer diagnostics is to make it easier and faster to find out what’s going on with your vehicle. Today’s testing equipment produces accurate reports in minutes, eliminating the guesswork of auto diagnostics.

Our mechanics are highly skilled and understand the need to focus on all of the small details. We work with residents all over Phoenix, AZ to diagnose auto issues and get them fixed before they cause some other problem.

When your check engine light comes on or the engine misfires just once, that’s reason enough to come see us.

You may be thinking ‘engine replacement’ with dollar signs flashing in your eyes, but a simple test – after just one sluggish start – can relieve your worries and cost about $20 for the part plus a little more for labor instead of that $4,000 to replace the engine.

They will have computer codes directly from your on-board computer, as well as charts and graphs, information from the vehicle’s sensors and an accurate report of the exact software your vehicle uses so that all the information we receive can be accurately interpreted. Even though auto diagnostics is a high-tech tool, our mechanics still have to know what to do with the information it produces.

Although the problem has been recognized by the auto maker, it may not be a problem we have seen yet. Therefore, we have to keep our technicians abreast of every possibility and new development so they can accurately use the information our diagnostic equipment produces.

When you have to leave it behind at the shop – first to find out what the problem is, then to actually make the repairs – you could be without a way to travel for days or weeks. That’s inconvenient and can get pretty expensive if you have to rent a car or make some other arrangements to get back and forth to work and events.

Chelsee’s technicians are well aware that your vehicle is your livelihood and your connection to the outside world. That’s one of the main reasons we use computer diagnostics as a part of our full-service car care.

For example, your transmission fluid may not be low yet, so a diagnostic evaluation may not pick up any system errors yet, but a visual inspection may reveal that transmission fluid has leaked underneath your car. We always try to verify our results with what the computer says, but there’s no substitute for our experience and deep knowledge of common and not-so-common auto repair issues and their solutions.

We promise fast-turnaround time for your diagnostic. Our mechanics use the right tools for any job and have access to some of the latest technology so that they can perform high-quality work.

This final check takes just minutes, but it saves us and the customer a lot of stress and frustration if the initial repair doesn’t fully fix the problem. No matter what method we use to successfully locate the problem, our technicians work efficiently so that auto repair jobs get done promptly, and we always explain our findings in an understandable manner.

One of the most misunderstood indicators on your dashboard is the check engine lights. It could be on because your gas cap is loose (That’s an easy fix.

Your vehicle’s check engine light can be a source of anxiety and confusion. When that ominous light illuminates on your dashboard, it’s natural to wonder, “Why is my check engine light on.

Surprisingly, a loose or improperly sealed gas cap is a common culprit. This can trigger the check engine light as it can lead to evaporative emissions.

A malfunctioning sensor can lead to reduced fuel efficiency and increased emissions. These are essential for igniting the fuel-air mixture in your engine.

A failing catalytic converter can trigger the light. It’s crucial for reducing harmful emissions.

When it’s faulty, it can affect engine performance. The ignition coil sends power to the spark plugs.

The EGR valve helps reduce emissions by recirculating a portion of exhaust gases into the intake manifold. A faulty valve can trigger the check engine light.

A malfunctioning injector can affect engine performance. Various sensors and their associated wiring can become damaged, leading to a check engine light.

In any case, when your check engine light comes on, it’s essential to have a check engine light diagnosed by a qualified mechanic. Ignoring it can lead to more significant problems down the road.

A check engine light diagnostic scan can pinpoint the exact problem, allowing for a swift and accurate repair. Visit Advance Automotive for engine light diagnostic today.

If your diagnostic system detects a problem in the electronic control system that it is not able to correct, the vehicle’s computer will turn on the check engines warning light. When your check engine lights is lit, your vehicle might be releasing excessive pollutants into the air or consuming too much fuel.

If your check engine lights is flashing, your vehicle’s computer system has detected a potentially dangerous systems issue and it is not safe to drive your car. If you require towing assistance, please contact us.

In addition to the warning light, your vehicle stores a trouble code in its computer’s memory that indicates the source of the problem. While the trouble codes stored in your vehicle’s computer can point to the symptoms of the problem, they can’t specifically identify the cause.

Don’t wonder any longer: Advanced Automotive Inc. can diagnose the problem quickly and effectively.

Surprise. It won’t start.

If you have no idea where to begin, it sure will be difficult to repair it. There are a lot of reasons why your car won’t start: – Faulty starter motor – Low voltage/Bad car battery – Bad fuel pump – Faulty crankshaft sensor – Faulty ignition coil – Faulty ignition switch – Faulty ignition relay/main relay.

Check the car battery first before worrying about the starter motor, fuel pump, or ignition repairs. Experts will tell you that a lot of the time, the car simply needs a new battery.

When diagnosing why the car is not starting, do the battery eye test. Safety first, so apply the parking brake and make sure the ignition is off.

If you see most of these on the battery, then you know the reason for your car starting problems, and it is time to get a new car battery. But how do you swap the battery yourself.

It will help you remember how to reconnect the new battery, especially if you have never done it before. It is always best to have experts replace the battery, but if you are determined to do it yourself, let’s look at the next steps.

If you disconnect the red cable first and touch any metal surface, you could create a spark that damages the electrical system. The battery is kept safe by restraints that are either a clip holding it in place at the bottom or a bar on top.

If you see dirt, give the area where your old battery was a quick wipe. Put the new battery in and fasten the restraints.

First connect the red cable, then the black cable. The new car battery should be fully charged when you buy it.

What else can cause a car not to start when you put in a new battery.

If you know your engine is cranking, you can go to the next step. You can typically hear it from the starter’s sound when turning the ignition.

If your engine is not cranking, ensure that the car battery is charged and in working order. You can either try to jump-start the battery from another car or with the help of a booster pack.

If the battery is good and the jump start didn’t help the engine to crank, there is most likely a problem with your starter or the electrics to it. The next step is to test the wires on the starter.

Check the ground between the engine and the body. You can put a jumper cable between the battery negative terminal and a good ground point on the engine to check if it’s bad ground.

Check if you get 12V on the small wire when you are turning the ignition switch to the starter position. Keep your hands away from any moving parts while doing it.

It’s rare for the massive power cable to the starter to get damaged, so to be 100% sure that’s the cause, you have to perform a loading test on the wire. If you have done a loading test and it shows OK, and you get 12V on the small cable when cranking, you have a faulty starter, and it has to be replaced.

If the car is cranking, but won’t start, use an OBD2 scanner to find out if there are any stored trouble codes in the trouble code memory. By reading the trouble codes, you can skip over many troubleshooting steps and jump directly to troubleshooting the part you got the trouble code for.

You can find the information about the trouble codes in the OBD2 codes. If you have an older American vehicle, there is a chance that you have OBD1 codes and you do not need a scanner to read them.

You can do this by checking your tachometer for any RPM readings on the dashboard. Even better is to check the value of the crankshaft RPM from the engine control unit with an OBD2 scanner.

In more advanced troubleshooting you can also check the signals from the crankshaft and camshaft sensors with an oscilloscope to see if the signal looks good or not, but in most cases, you can only make corrections if you are getting any RPMs in the engine control unit and make sure there are no trouble codes stored.

A bad fuel pump, clogged fuel filter or a bad fuel pressure regulator can result in low fuel pressure which will lead to your car might not starting. Low fuel pressure is a widespread cause of why your car won’t start.

If it’s equipped with a fuel pressure sensor, you will likely also get a trouble code showing low fuel pressure. But it’s always good to verify it with a manual fuel pressure gauge.

If it’s not going, but you get voltage to it, replace the fuel pump. If the fuel pump is fine, replace the fuel filter and troubleshoot the fuel pressure regulator.

It could either be caused by a bad spark plug, bad ignition coil or ignition cable. The wirings could also point to the ignition coil or to no signal from the crankshaft sensor, so you should always diagnose the crankshaft sensor first.

Take a cable between the plug and a good ground point and let a friend crank the engine while you are checking for a spark, just remember to keep your hands away from the spark or you will get a dangerous shock. Another common cause – is the injectors are not opening and injecting fuel into the engine.

You can measure the voltage with a multimeter to check if the injectors are opening. The injectors usually do have two pins, one 12+ power and one ground signal to the engine control unit.

More advanced troubleshooting of the injectors should be done with an oscilloscope. When the fuel injectors are opening, they are often making a small clicking sound which you can hear if you listen carefully.

If they are clicking, the injectors shouldn’t have a problem. You can also take a look at the spark plugs – if the car is injecting fuel, they will be wet but produce no sparks.

Almost all engines have TDC marks where the camshaft and the crankshaft should be aligned. You have to find these marks either in the repair manual for your car or online.

A timing belt or a timing chain that has jumped over will in almost all vehicles result in damaged valves. If you suspect that your chain or belt has skipped over, you should always make a compression test to verify that the compression is good and the valves are not bent.

First, you should make a compression test with a compression tester to verify that you have the same pressure on all cylinders. Check the repair manual to see what pressure the engine should have.

A leak-down test is meant to help you see if there is any pressure going through the piston rings down to the bottom of the engine. This can be a good method to recognize broken pistons and piston rings.

Your company will have rules when there is a fleet car breakdown or it does not start. They.

Chances are good that you’ve dealt with the check engine light, but unlike other problems, the check engine light can seem like a mystery. For example, if you have a squeaky serpentine belt, the solution is often quite obvious – replace the serpentine belt.

The check engine light isn’t quite so self-explanatory. While the engine in your vehicle is quite similar to that made a century ago, the engine control module (ECM) makes it possible to extract power more efficiently.

The ECM monitors the engine, constantly tuning engine output to driver demand, such as passing power or cruising fuel economy. Let’s say your check engine light comes on, but you don’t really notice it because the car seems to run well enough.

The problem you now face is what to do about the check engine light. There are literally thousands of diagnostic trouble codes (DTCs) that the check engine light might refer to.

Some auto repair shops charge for auto diagnostic services, but some places, such as autoparts stores, offer to scan your vehicle for free. You are probably wondering, “Why should I pay for auto diagnostic service when someone will do it for free.

Today, it seems that more people are “price shopping” than ever before, but this doesn’t really help anyone. As the saying goes, “You get what you pay for,” and this is especially true in the auto repair field.

The truth is, at best, you’ll get a printout of the DTC and a “guess” as to what the problem might be. It’s an autoparts store, after all, and their business is selling parts, not necessarily fixing cars.

In the end, you got a “free” auto diagnostic check, but you wasted time and money on unnecessary parts. Where’s the value in that.

On the other hand, if you pay for auto diagnostic service (the average is between $100-$120) where’s the value in that. Most auto repair shops employ ASE-Certified technicians, who spend thousands of hours in training and working on cars every day, and also maintain thousands of dollars in modern auto diagnostic and repair tools.

Essentially, the ECM is telling us that the air-fuel ratio is incorrect, that is, it is detecting too much air or too little fuel. One of the most misdiagnosed DTCs, because it’s an “oxygen sensor code,” many simply jump to the conclusion that the oxygen sensor needs to be replaced – perhaps all of them “because you need to be sure.” After spending a thousand dollars on oxygen sensors, the check engine light comes back on.

Diagnosing the fuel system includes testing everything related to air and fuel, including fuel pressure, intake and exhaust, and electronic testing of the air metering system, to name a few. It’s time well-spent, because the technician finds an intake air leak skewing oxygen sensor readings.

True, this is just one example, but it goes to show that paying for competent auto diagnostic services is worth your time and money. The next time you are in need of and auto diagnostic check, ask yourself if “free” is the same as “value.”.

Then, we’ll give you an estimate of any parts or repairs needed. We think you’ll agree that, for auto diagnostic services, Dobbs Tire & Auto Centers is worth your consideration, where we offer real value for your time and money.

A car’s “check engine” light is so mysterious. “Something is wrong.

What is wrong. Is my engine about to explode.

The light just sits there, shining at you. “Check it.

Since 1996, new cars sold in the U.S. are required to have onboard diagnostics (OBD) systems that allow mechanic can plug in a device and receive a code from the car’s computer that narrows down the source of a problem.

The device—called an OBD2 or OBD-II scanner—will give them a number they can then look up and find out what might be wrong. This isn’t just for the check engine light, either.

You can buy a cheap OBD2 reader to check basic codes yourself, or a fancy one to get more information. But you don’t need to buy a scanner or book an appointment at the dealership just to find out a code reading.

Many auto parts stores offer code readings as a free service. Advance Auto Parts, AutoZone, and O’Reilly are among the stores that will.

Check with your local store to find out whether they offer this service, and whether it’s free.). Knowing the code may not tell you exactly what’s wrong with your car, but it can narrow down the type of problem you’re having.

For example, there is a code that indicates a leak in the emissions control system. It’s often triggered by your gas cap being loose.

There are other codes that would indicate if something is wrong with the catalytic converter, or if the engine is misfiring.

They offer this service because people will often check their diagnostics, then buy a part to fix whatever is wrong. So if the problem is straightforward, you might be on your way pretty quickly—but if not, you’ll at least have a better idea of whether you really need to book that mechanic’s appointment.
