If your check engine light is flashing in your Chevy Blazer, we highly recommend not to drive the vehicle and schedule Chevy service today. Below is a list of the most common reasons your check engine light can come on:

• The battery is low or dead. The battery in your Chevy Blazer is each critical. Without a vehicle battery, your vehicle won’t start, light up the road in front, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't absolutely require maintenance. The price of a new one depends on the type of Chevy you drive, but check our current service coupons and specials.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Chevy Blazer if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound familiar, bring your Blazer to Chevy and have our team of gifted certified mechanics make sure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, exceptionally aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could help you save considerably from having to get poor work and damage caused by poor installation work corrected.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Chevy Blazer is what determines how much fuel is necessary to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your Chevy Blazer is having trouble starting, idling rough or has a sudden fast change in the position of the throttle pedal, this could be a vital sign of a broken mass airflow sensor.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns more promptly and your car will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A broken sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your Chevy Blazer's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the absolutely correct mixture of air and fuel that enters the cylinders in your engine. A broken O2 sensor can still cause a vehicle to fail an emissions test.
• One of the most common and frequent cause is that your Chevy Blazer gas cap is loose, damaged or missing. The gas cap for your Chevy Blazer serves numerous purposes. It prevents unpredictable gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a broken fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump and be more costly. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on instantly after you put gas in your Chevy Blazer, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your Chevy Blazer’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is usually caused by constantly neglected maintenance, which is why Bill Estes Chevy Indianapolis offers a complimentary multi-point examination with each Chevy service. If you have an issue with your catalytic converter and don't get it repaired, your Chevy Blazer will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other perilous problems from overheating.
• Your Chevy Blazer has a vacuum leak. Each Chevy Blazer has a vacuum system that performs a wide variety of functions. The vacuum system still helps lower unhealthy emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, exceptionally if they’re exposed to intense heat or extreme cold.
• New Spark Plugs or Plug Wires are necessary for your Chevy Blazer. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your car. This explosion is what moves the pistons and makes the engine run smooth. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or old, you will experience a evident poor performance and decreased power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more expensive repairs.

Check Engine Light Service Chevy Blazer

What do you do when you’re driving along in your Chevy Blazer and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Chevy owners, your heart sinks drastically because you may have precisely idea about what that light is trying to tell you or how you should react.

When your Chevy Blazer's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is typically labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that can quickly identify the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Chevy auto repair mechanics at Bill Estes Chevy Indianapolis. There are likewise a number of comparatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the exactly correct issue and repair it.
