Code P101A 2016 Honda CR-V Description

The variable Valve Timing Control (VTC) system controls the phase of the intake camshaft and exhaust camshaft. It uses oil pressure to operate the VTC actuator 'B' so the valve timing is optimized depending on driving conditions. The Powertrain Control Module (PCM) monitors the phase control command value and the actual phase value of exhaust camshaft using the Camshaft Position (CMP) Sensor 'B'. When an over-retarded camshaft phase angle, which the over-retarded angle is predetermined value greater than the commanded values, continues to exist while the VTC is either active or inactive or a retarded phase angle of the exhaust camshaft is greater than the predetermined value while the VTC is inactive, a malfunction is detected and a DTC is stored.
