Group 1 Chevrolet Northwest welcomes you to discover the reasons why your Chevrolet check engine light has turned on.
The check engine light warns drivers of future engine issues or failure. There are lots of reasons your vehicle’s check engine warning light might turn on. It might be small things like sensor failure, an alert to perform preventive maintenance, or even warning drivers of potentially significant problems that could cause engine failure. So, just because the check engine warning light is triggered, it might not be a total catastrophe. However, when your check engine warning light does come on, you ought to bring it to us for a full inspection. Even if nothing feels broken, having it diagnosed can be the difference between needing to replace the engine and a cheap repair.
Something as simple as not replacing the gas cap or not tightening it completely could easily cause a check engine light. Your car’s gas cap may need to be replaced during your ownership. After 50,000 miles, you may want to replace the gas cap. We highly recommend genuine OEM replacement parts if it’s time to replace your gas cap. Replacement parts from big box stores will work in a pinch, but nothing is better than original parts from the manufacturer.
There are many sensors that feed information to the vehicle’s engine to help it work efficiently. However, bad readings from components like the MAF sensor or the O2 sensors can trigger a check engine light to come on. If your vehicle is running like normal, a broken O2 sensor is the most likely culprit. This may mean that the car is probably fine, but since the engine isn’t receiving the info, it triggers the warning. Even if your vehicle feels fine, you should get it diagnosed immediately to rule out any potential larger issues.
Spark plugs are essential to the performance of your engine. As the name indicates, spark plugs give off a small spark of electricity, which then ignites the fuel and causes the engine to run. Spark plugs have exact measurements for peak performance, and if the spark plug configuration is incorrect, it could trigger a check engine warning light. Symptoms of faulty spark plugs include lower MPG rates, less engine power, and an engine that just will not run smoothly.
