MONITOR DESCRIPTION
This DTC is output when a malfunction in the cam timing control motor rotation sensor is detected. The cam timing control motor with EDU assembly is equipped with a self diagnostic function, which is used to output diagnosis signals (VTM) to the ECM. If the ECM receives a duty signal of 40%, this DTC is output immediately (1 trip detection logic).

CAUTION / NOTICE / HINT
HINT:
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
