Why Is My Honda Check Engine Light Illuminated?

why is my honda check engine light illuminated?


Fernandez Honda welcomes you to discover why your Honda check engine light is illuminated.

The check engine warning light warns drivers of possible engine problems or even failure. Your vehicle’s check engine light might come on because of several reasons. It might be anything from a simple sensor failure, an alert to schedule preventive maintenance, or even warning of potentially significant problems that could contribute to engine failure. So, even if the check engine light is triggered, it may not be a complete disaster. However, if your check engine warning light does come on, we suggest bringing it to us for a complete diagnostic inspection as soon as possible. Even if nothing seems broken, having it inspected can mean the difference between having to replace the engine and a cheap repair.


Failing Gas Cap

Your Gas Cap is Not Fully Tightened

Something as basic as forgetting to replace the gas cap or not tightening it completely could easily cause a check engine light. A gas cap may need to be changed during your ownership. Gas caps may have a life expectancy as low as 50,000 miles. If you feel you should replace your gas cap, we highly recommend genuine replacement parts from the manufacturer. Using parts from Do-It-Yourself stores can work in an emergency, but nothing is better than OEM parts.

Old O2 Sensors

Old O2 Sensors

Several sensors give information to the car’s engine to help it run more efficiently. However, bad sensor readings from components like the MAF sensor or the oxygen sensors can cause a check engine light to come on. If the vehicle is running like it should, an old oxygen sensor is the likely culprit. In this situation, it might mean that your vehicle is actually running normally, but because the engine isn’t getting the info, it triggers a warning light. Even if the car feels unaffected, you should get your car checked out immediately to rule out any potential larger issues.

Faulty Spark Plugs

Spark Plugs in The Car are Failing

Spark plugs are vital to the efficiency of your car’s engine. As the name indicates, they give off a tiny spark of electricity that ignites the fuel and causes your engine to run. Spark plugs demand very precise tolerances for optimal effectiveness, and if the spark plug configuration is wrong, it could trigger a check engine light. Some symptoms of old spark plugs include diminished MPG rates, less engine power, and an engine that just does not run smoothly.
