A check engine light can be one of the most frustrating and confusing things to see while you're driving. It's a warning that something is wrong with your vehicle, but it doesn't give you any specific information about the problem.

The check engine light is triggered by a sensor that is located in the vehicle's engine. These sensors are designed to monitor various systems in the vehicle, such as the engine, transmission, and emissions systems. If a sensor detects a problem, it will send a signal to the onboard computer, which will then turn on the check engine light.
