Check Engine Light
Your Check Engine Light (CEL) warns you that your vehicle’s computer found a malfunctioning component in your emission control system. You may see “check engine,” “service engine soon,” or “check powertrain.” Or, the light may show an engine picture, perhaps with the word “Check.” To determine the actual problem, we use an electronic scan tool or a diagnostic computer to retrieve Diagnostic Trouble Codes (DTC). Some common issues that turn on the check engine light include:
- Your gas cap isn’t on tight enough; we suggest checking before calling us
- Water got into your engine somewhere
- The spark plugs don’t function correctly
- Your vehicle is emitting high levels of pollutants
In any case, you should bring your vehicle to us, and we can inspect your vehicle, diagnose the problem, and take care of it. Leaving your engine light on can cause serious problems with your car in the long run.
A check engine light appointment goes pretty fast, so stop by or give us a call.
Frequently Asked Questions
A check engine light is triggered by your car’s computer when one of the dozens of sensors on your vehicle report back values that are out of range. It can be caused by something as simple as a loose gas cap, and something as specific as a mass air flow sensor. Our expert technicians can pull the code and investigate the system to find out what caused the problem.
No – all the code tells us is where the fault was measured – NOT what went wrong. To put it another way, it’s like a code telling you that your leg pain is in your knee – but that doesn’t tell you if it’s your ACL, MCL, Patellar tendons, or something else entirely.
