Code P15C0 Honda Description

The engine mount control system controls the engine mounts electronically. The system consists of the active control engine mount (ACM) 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 ACM actuators to command the engine mounts to push and pull on the engine to counteract the engine vibration. The PCM monitors the CKP signal input to the engine mount control unit, and when an abnormal condition continues for a set time, the PCM detects a malfunction and a DTC is stored.
