Code P15BF Description

The engine mount control system controls the engine mounts electronically. The system consists of the engine mount actuators, the engine mount control unit, and the Powertrain Control Module (PCM). The engine mount control unit uses the crankshaft and camshaft position sensor outputs (received from the PCM) to estimate engine vibration. The engine mount control unit then sends signals to the engine mount actuators to command the engine mounts to push and pull on the engine to counteract the engine vibration. The PCM monitors the CMP signal input to the engine mount control unit. If the CMP signal is not input to the engine mount control unit for a set time, the PCM detects a malfunction and a DTC is stored.
