This DTC is output when a malfunction in the intake side camshaft timing control motor's rotation sensor is detected. The camshaft timing control motor is equipped with a self diagnostic function, which is used to output the duty ratio (when normal: 70 to 90%) as a signal (VTM) to the ECM. If the ECM receives a duty signal of 40%, a DTC is output immediately (1 trip detection logic).
