Code P16C6 Honda 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 engine vibration. The engine mount control unit monitors the engine mount control unit voltage. If the ACM RLY OUT voltage is set value or less for a set time, the engine mount control unit detects a malfunction and stores a DTC.
