Why Is My Chevrolet Check Engine Light Active?

why is my chevrolet check engine light active?


Bob Howard Chevrolet welcomes you to discover why your Chevrolet check engine light is active.

The check engine light warns owners of future engine problems or failure. There are many reasons your car’s check engine light might turn on. It might be small things like a simple sensor failure, alerting you to do preventive maintenance (such as an oil change), or even warning of major issues that may cause engine failure. So, just because the check engine warning light turns on, it might not be a total catastrophe. However, if and when your check engine warning light does come on, you should bring it to us for a thorough inspection as soon as possible. Even if nothing feels broken, getting it inspected can be the difference between having to replace the engine and a simple fix.


The Gas Cap is Failing

The Gas Cap is Old

Something as silly as forgetting to replace your gas cap or not replacing it correctly could easily cause a check engine warning light. The vehicle’s gas cap will probably need to be replaced during your ownership. Gas caps may last only 50,000 miles. If it’s time to replace your gas cap, we recommend genuine replacement parts from the manufacturer. Parts from DIY stores will work in an emergency, but nothing is better than parts from the manufacturer.

Oxygen Sensors in Your Vehicle are Faulty

O2 Sensors in The Car are Faulty

Several sensors give information to the engine to help it work more efficiently. However, missing readings from components like the MAF sensor or the O2 sensors can trigger a check engine light. If the vehicle seems normal, a faulty O2 sensor is the most likely reason. In this situation, it may mean that your vehicle is running normally, but since the engine isn’t receiving the information, it triggers a warning. Even if your vehicle feels normal, you should probably get it diagnosed ASAP to rule out any potential more significant problems.

Spark Plugs in Your Vehicle are Faulty

Spark Plugs in Your Vehicle are Bad

Spark plugs are essential to the performance of your vehicle’s engine. As the name indicates, they give off a tiny spark of electricity that ignites the fuel and causes the engine to run. Spark plugs have very precise tolerances for peak performance, and if the spark plug gap is wrong, it could possibly trigger a check engine warning light. Some symptoms of worn spark plugs include lower fuel efficiency, less engine power, and an engine that just will not run smoothly.
