If there is a difference between the oil pressure condition in the hydraulic circuit that is determined by the ECM/PCM command and the oil pressure condition that is determined by the status of the VTEC oil pressure switch, the system is considered faulty and a DTC is stored. The ECM/PCM monitors oil pressure in the hydraulic circuit of the VTEC mechanism using the VTEC oil pressure switch downstream of the VTEC solenoid valve. The Diagnostic Trouble Code (DTC) was P2646: VTEC Oil Pressure Switch Circuit Low Voltage.ĭescription: The VTEC system activates the VTEC solenoid valve from the engine control module (ECM)/powertrain control module (PCM) and it charges/discharges the hydraulic circuit of the VTEC mechanism that switches valve timing between Low and High.
