★ Top Answer
The 7e8 engine code on a GMC Terrain signals that the knock sensor has detected engine vibrations that could potentially cause damage. While the knock sensor is able to detect vibrations that are imperceptible to the human ear, allowing them to persist could harm the engine. If the sensor is malfunctioning and not flagged with an error code, there is a risk of engine damage. To avoid problems, it is important to get the vehicle checked by a mechanic if the sensor is showing an error code. Ignoring the issue could lead to further complications down the road.
