Engine codes are diagnostic trouble codes (DTCs) that are stored in the vehicle’s engine control module (ECM). These codes are used to identify the source of a problem with the engine, such as a faulty sensor or a mechanical issue. When an engine code is triggered, the check engine light will illuminate on the dashboard.
There are several ways to clear engine codes. One way is to use a code reader or scanner. These devices can be plugged into the vehicle’s diagnostic port and will read the stored engine codes. Once the codes have been read, they can be cleared using the code reader or scanner.
