What Does It Mean When My Acura Check Engine Light Symbol Is Lit?

what does it mean when my acura check engine light symbol is lit?


Come to Hubler Acura to learn what it means when your Acura check engine light symbol is lit.

The check engine warning light warns drivers of future engine problems or even complete failure. Your check engine warning light may come on because of several reasons. It could be everyday problems like sensor failure, alerting you to perform maintenance (such as an oil change), or even warning of major issues that might cause engine failure. So, even if the check engine warning light comes on, it might not be a total disaster. However, if your check engine warning light does come on, you should bring it to us for a complete inspection. Even if nothing acts broken, having it inspected can mean the difference between a cheap repair and needing to replace the engine.


Oxygen Sensors in Your Vehicle are Old

Oxygen Sensors in Your Vehicle are Faulty

Several sensors provide info to the engine to help it work efficiently. However, bad sensor readings from components like the mass airflow sensor or the O2 sensors can trigger a check engine light to come on. If your car seems normal, an old O2 sensor is the most likely reason. This could mean the vehicle is actually running normally, but because the engine isn’t receiving the data, it triggers a warning light. Even if your car feels normal, you should get your car checked out immediately to rule out any potential larger issues.

Your Gas Cap is Failing

Loose Gas Cap

Something as simple as not replacing the gas cap or not tightening it completely may cause a check engine light. The gas cap might need to be changed during your ownership. After 50k miles, you should consider replacing your gas cap. If you feel you need to replace your gas cap, we highly recommend genuine OEM replacement parts. Using parts from big box stores will work in an emergency, but nothing beats OEM parts.

Spark Plugs in Your Vehicle are Old

Bad Spark Plugs

Spark plugs are essential to the efficiency of your engine. As the name suggests, spark plugs provide a small spark of electricity, which then ignites the fuel and causes your engine to run. Spark plugs demand accurate measurements for optimal performance, and if the spark plug gap is too large, it could possibly cause a check engine warning light. Some symptoms of faulty spark plugs include lower fuel economy, less engine power, and your engine just does not run smoothly.
