Cooling Fan

WARNING: This page is about a different car, the 1994 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

The PCM regulates operation of the electric cooling fan through a PCM-controlled relay, which controls the ground or power circuit of the cooling fan. This allows the PCM to operate the cooling fan based on engine temperature. A malfunction of the cooling fan will cause engine overheating and possible detonation.
