If your check engine light is flashing in your Chevy Silverado, we extremely propose 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:

  • Your Chevy Silverado has a vacuum leak. Each Chevy Silverado has a vacuum system that performs a wide variety of functions. The vacuum system still helps lower harmful 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, particularly if they’re exposed to intense heat or extreme cold.
  • One of the most common and frequent cause is that your Chevy Silverado gas cap is loose, broken or missing. The gas cap for your Chevy Silverado serves various purposes. It prevents dangerous 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 faulty 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 immediately after you put gas in your Chevy Silverado, 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.
  • The battery is low or dead. The battery in your Chevy Silverado is each important. Without a vehicle battery, your vehicle won’t start, light up the road ahead, 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.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Chevy Silverado is what determines how much fuel is needed 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 Silverado is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a critical sign of a faulty mass airflow sensor.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Chevy Silverado if it’s not installed accurately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound familiar, bring your Silverado to Chevy and have our team of accomplished certified mechanics guarantee that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or utilizing 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 catalytic converter is bad or going bad. The catalytic converter is a part of your Chevy Silverado’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A broken catalytic converter is ordinarily caused by regularly neglected maintenance, which is why Coggin Chevrolet at the Avenues offers a complimentary multi-point check with each Chevy service. If you have an issue with your catalytic converter and don't get it repaired, your Chevy Silverado 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 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 quickly and your vehicle will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your Chevy Silverado's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the absolutely correct combination of air and fuel that enters the cylinders in your engine. A faulty O2 sensor can still cause a vehicle to fail an emissions test.
  • New Spark Plugs or Plug Wires are needed for your Chevy Silverado. The spark plugs are the part of your engine that ignites the air/fuel combination in the combustion chamber of your vehicle. 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 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.
