There is a screen on the VTC assembly gasket that needs to be checked, as well as on the oil control valve
This means the sensor is indicating that the oil pressure value is too low, which is due to faulty sensor, faulty sensor circuit or low oil level If there is a disparity between oil pressure condition in the hydraulic circuit that is determined by the 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 . Please see OBD1 wiring notes below Wiring: Many common OBD1 and OBD2 JDM engines do not have a VTEC Oil Pressure Switch If it shows zero on the oil gauge, it is a good sender and is not faulty .
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 rocker arm oil pressure switch (VTEC oil pressure switch), the system is considered faulty, and the Diagnostic Trouble Code (DTC) is stored
