Engine Oil Pressure Gauge

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 will display the low oil pressure message on the DIC.
^ The check gages indicator turns on.
