The check engine light is a warning light on a vehicle’s dashboard that indicates a problem with the engine or emissions control system. When the check engine light is on, it means that the vehicle’s computer has detected a problem and has stored a diagnostic trouble code (DTC) in its memory. The DTC can be used to identify the specific problem that is causing the check engine light to come on.
There are a number of different ways to reset the check engine light. One common method is to simply disconnect the battery for a few minutes. This will cause the vehicle’s computer to lose power and reset the DTCs. However, this method will also reset other settings in the vehicle’s computer, such as the radio presets and the clock. Another method is to use a code reader to clear the DTCs. A code reader is a device that can be plugged into the vehicle’s diagnostic port and used to read and clear DTCs.
