What could trigger the check engine light in my 2015 Lincoln MKC to illuminate?

Question

Accepted Answer

In the 2015 Lincoln MKC, you cannot manually reset the check engine light yourself. This light indicates a problem with the car, which could be caused by various issues. It is not worth your time to try to pinpoint a random problem unless it is obvious. The best course of action is to take the car to a mechanic who can use an OBD tool to scan and retrieve the trouble code, pinpointing the issue. Once you know the problem, you can proceed with getting it fixed, which will then turn off the light. However, it is advisable to first check the gas cap and fuel door - if the cap is missing or the door is open, it can trigger the light unnecessarily. Checking this first can save you a trip to the mechanic for a minor issue.
