The check engine light warns owners of future engine issues or complete failure. Your vehicle's check engine warning light may turn on due to several reasons. It may be everyday problems like sensor failure, an alert to perform preventive maintenance (such as an oil change), or even warning drivers of potentially significant problems that might cause engine failure. So, just because the check engine light is triggered, it might not be a complete catastrophe. However, when your check engine light does come on, we suggest bringing it to us for a complete diagnostic inspection. Even if nothing acts broken, having it diagnosed accurately can be the difference between having to replace your engine and a simple fix.
There are sensors that give information to your engine to help it run efficiently. However, missing readings from components like the MAF sensor or the oxygen sensors can trigger a check engine warning light. If the car seems normal, a broken oxygen sensor is the most likely culprit. This might mean your car is actually running normally, but because the engine isn't getting the info, it triggers a warning. Even if the car feels fine, you should get your car checked out ASAP to rule out any potential larger issues.
Spark plugs are vital to the performance of your vehicle's 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 very precise measurements for peak performance, and if the spark plug configuration is incorrect, it could cause a check engine warning light. Some symptoms of worn spark plugs include diminished fuel efficiency, slower acceleration, and your engine just does not run smoothly.
Something as simple as not replacing your gas cap or not replacing it completely may trigger a check engine light. A gas cap will probably need to be changed during your time of ownership. After 50,000 miles, you should consider replacing your gas cap. If it's time to replace your gas cap, we highly recommend genuine OEM replacement parts. Using parts from Do-It-Yourself stores will work in a pinch, but nothing is better than original parts from the manufacturer.
