Why Is My Genesis Check Engine Light On?

why is my genesis check engine light  on?


Genesis of Southwest Houston invites you to find out why your Genesis check engine light is on.

The check engine light warns drivers of possible engine issues or failure. Your check engine warning light may turn on because of several reasons. It may be anything from a simple sensor failure, an alert to schedule maintenance, or even to be on the lookout for potentially significant issues that could contribute to engine failure. So, just because the check engine warning light is triggered, it may not be a total disaster. However, if and when your check engine warning light does come on, you ought to bring it to us for a complete inspection. Even if nothing seems broken, getting it inspected can be the difference between a simple fix and having to replace your engine.


Your Gas Cap is Not Fully Tightened

Your Gas Cap is Failing

Something as simple as not replacing your gas cap or not replacing it correctly may cause a check engine warning light. Your car’s gas cap may need to be replaced during your time of ownership. Gas caps may have a life expectancy as low as 50,000 miles. We highly suggest genuine replacement parts from the manufacturer if you feel you need to replace your gas cap. Using parts from Do-It-Yourself stores will work in a pinch, but nothing is better than OEM parts.

O2 Sensors in The Car are Faulty

Bad Oxygen Sensors

Several sensors give info to your engine to help it run more efficiently. However, missing readings from components like the mass airflow sensor or the O2 sensors can cause a check engine light to come on. If your vehicle is running like it should, a broken O2 sensor is the most likely reason. This could mean that the vehicle is running normally, but because the engine is not receiving the data, it triggers the warning. Even if your car feels fine, you should probably get your car checked out immediately to rule out any potential larger issues.

Faulty Spark Plugs

Spark Plugs in Your Vehicle are Bad

Spark plugs are essential to the performance of your car’s engine. As the name indicates, they give off a spark of electricity that ignites the fuel and causes your engine to run. Spark plugs have very precise measurements for peak performance, and if the spark plug configuration is too large, it could trigger a check engine warning light. Symptoms of worn spark plugs include lower fuel efficiency, slower acceleration, and an engine that just doesn’t run smoothly.
