If your check engine light is flashing in your 2020 Chevrolet Blazer, we tremendously advocate not to drive the car and schedule Chevrolet service today. Below is a list of the most common reasons your check engine light can come on:

• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2020 Chevrolet Blazer if it’s not installed accurately. 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 Chevrolet and have our team of skilled certified mechanics assure that your aftermarket items were installed properly 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 Chevrolet Blazer is what determines how much fuel is required 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 Chevrolet Blazer is having trouble starting, idling rough or has a sudden fast change in the position of the throttle pedal, this could be a essential sign of a damaged mass airflow sensor.
• One of the most common and frequent cause is that your 2020 Chevrolet Blazer gas cap is loose, damaged or missing. The gas cap for your 2020 Chevrolet Blazer serves various purposes. It prevents perilous 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 damaged 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 expensive. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on promptly after you put gas in your 2020 Chevrolet 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.
• New Spark Plugs or Plug Wires are required for your 2020 Chevrolet Blazer. The spark plugs are the part of your engine that ignites the air/fuel mix 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 noticeable poor performance and reduced 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.
• Your 2020 Chevrolet Blazer has a vacuum leak. Every Chevrolet Blazer has a vacuum system that performs a wide variety of functions. The vacuum system still helps lower adverse 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.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2020 Chevrolet 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 ordinarily caused by repeatedly neglected maintenance, which is why Coggin Chevrolet at the Avenues offers a complimentary multi-point inspection with every Chevrolet service. If you have an issue with your catalytic converter and don't get it repaired, your 2020 Chevrolet 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 delicate problems from overheating.
• 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 instantly 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 damaged sensor can not only affect your miles per gallon, but it can cause meaningful damage to your catalytic converter and your 2020 Chevrolet Blazer's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the specifically correct mix of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can still cause a vehicle to fail an emissions test.
• The battery is low or dead. The battery in your 2020 Chevrolet Blazer is every essential. 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 Chevrolet you drive, but check our current service coupons and specials.
