While cruising down the highway, you notice a warning light on your dashboard indicating an engine code issue. The code 7e8 points to a problem with the body control module detection. If the module is malfunctioning, it will have to be swapped out. The replacement part itself may set you back $120 to $185. Opting to have a professional mechanic or automotive service technician handle the replacement could add an extra $50 to $140 in labor fees.
In a Dodge Durango, if you see a 7e8 engine code pop up, it indicates an issue with the engine management settings in the control module.
