<center>What Does It Mean When Your Check Engine Light Symbol Is On?</center>
The check engine light warns drivers of potential engine issues or total failure. There are many reasons your car's check engine light may come on. It could be small things like sensor failure, an alert to do maintenance, or even warning drivers of potentially significant problems that might cause engine failure. So, even if the check engine light is triggered, it might not be a complete disaster. However, if your check engine light comes on, you ought to bring it to us for a complete inspection. Even if nothing acts broken, getting it inspected can mean the difference between having to replace your engine and a cheap repair.
Old Car Oxygen Sensors
There are sensors that provide info to the engine to help it work more efficiently. However, bad readings from components like the mass airflow sensor or the O2 sensors can trigger a check engine warning light. If the vehicle is running like it should, an old O2 sensor is the most likely reason. In this situation, it might mean your vehicle is running normally, but since the engine isn't receiving the information, it triggers a warning. Even if your car feels unaffected, you should get it checked out ASAP to rule out more serious issues.
Spark Plugs in Your Vehicle are Faulty
Spark plugs are vital to the efficiency of your vehicle's engine. As the name suggests, they provide a small spark of electricity, which then ignites the gas and causes an engine to run. Spark plugs require accurate measurements for peak performance, and if the spark plug configuration is too large, it could potentially trigger a check engine warning light. Some symptoms of worn spark plugs include lower fuel economy, slower acceleration, and an engine that just will not run smoothly.
Loose Gas Cap
Something as basic as forgetting to replace your gas cap or not tightening it completely may trigger a check engine warning light. The car's gas cap will probably need to be replaced during your vehicle ownership. Gas caps may last only 50,000 miles. We highly suggest genuine OEM replacement parts if it's time to replace your gas cap. Using parts from Do-It-Yourself stores will work in a pinch, but nothing is better than original parts from the manufacturer.
