Why The Check Engine Light Is On

Even though most people are terrified to see the malfunction indicator lamp light up, the reality is it doesn’t mean you’ll need expensive repairs. Unfortunately, you can’t determine what the issue is unless you check engine light diagnostics. One of the most common reasons is that your gas cap is loose or missing, cheap, and simple to correct. Another possibility is that your spark plugs and ignition coils need replacing. You may also have issues with your vehicle’s oxygen sensors, fuel injectors, mass airflow system, thermostat, catalytic converter, or other parts of your engine and emissions systems.

The malfunction indicator lamp can come on for various reasons, but it can give you some hints. The most important thing to note is whether or not the symbol is flashing. If the icon is steady, you should still have a professional determine the root cause before it gets worse. However, if the icon is blinking, you should immediately pull over and have it towed to our shop (we offer towing during normal business hours). Blinking means your engine is misfiring, damaging your catalytic converter, which is expensive to repair and replace. Our shop trains to handle any issue your car may have, so if your check engine light comes on, we’ll take care of it.
