Oil Pressure Gauge: Description and Operation

ENGINE OIL PRESSURE GAGE

The IPC displays the engine oil pressure as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine oil pressure. The engine oil pressure gage defaults to 0 kPa (0 psi) or below if:
- The PCM detects a malfunction in the engine oil pressure sensor circuit.
- The IPC detects a loss of class 2 communications with the PCM.
