DTC P2653: General Description
The variable cylinder management (VCM) system switches the valve timing by opening and closing the oil passage to the cam switching mechanism. The oil passage is opened and closed by the rocker arm oil control solenoid B (bank 1), and the powertrain control module (PCM) controls the VCM system via the rocker arm oil control solenoid B (bank 1). The PCM outputs the signal and monitors the PCM output terminal voltage level. When an abnormal condition continues for a set time, the PCM detects a malfunction and stores a DTC.
