Why Is My Nissan Check Engine Light Active?

Round Rock Nissan invites you to find out why your Nissan check engine light is active.

The check engine light warns drivers of potential engine problems or failure. There are lots of reasons your car’s check engine warning light may turn on. It could be anything from a simple sensor failure, an alert to perform preventive maintenance (such as an oil change), or even to be looking for major issues that could contribute to engine failure. So, just because the check engine light comes on, it may not be a total disaster. However, when your check engine warning light does come on, we suggest bringing it to us for a thorough inspection. Even if nothing acts broken, having it inspected can be the difference between having to replace the engine and a simple fix.

Your Gas Cap is Not Fully Tightened

Loose Gas Cap

Something as silly as not replacing the gas cap or not replacing it completely may cause a check engine warning light. Your vehicle’s gas cap might need to be replaced during your ownership. Gas caps may have a life expectancy as low as 50k miles. If you feel you need to replace your gas cap, we recommend genuine replacement parts from the manufacturer. Parts from Do-It-Yourself stores can work in an emergency, but nothing beats OEM parts.

O2 Sensors in Your Vehicle are Faulty

Faulty Oxygen Sensors

There are several sensors that provide information to your engine to help it work efficiently. However, bad readings from components like the mass airflow sensor or the oxygen sensors can trigger a check engine light. If the car seems normal, a broken oxygen sensor is the likely reason. In this situation, it could mean your car is actually running normally, but because the engine isn’t receiving the data, it triggers a warning light. Even if the car feels unaffected, you should get your car diagnosed immediately to rule out any potential more serious problems.

Spark Plugs in Your Vehicle are Faulty

Spark Plugs in The Car are Old

Spark plugs are essential to the performance of your engine. As the name implies, spark plugs provide a small spark of electricity that ignites the gas and causes your engine to run. Spark plugs demand exact measurements for peak performance, and if the spark plug setup is wrong, it could potentially trigger a check engine warning light. Some symptoms of worn spark plugs include lower MPG rates, slower acceleration, and your engine just will not run smoothly.
