DTC Advanced Diagnostics: P2653: General Description

Courtesy of HONDA, U.S.A., INC.

The powertrain control module (PCM) commands the rocker arm control solenoid to switches the valve timing by opening and closing the oil passage to the variable cylinder management (VCM) mechanism. If the malfunction detection signal is OFF (low) while the PCM outputs ON (high) to the rocker arm control solenoid, the PCM detects a malfunction and stores a DTC.
