Engine Oil Pressure Gage

The instrument panel cluster (IPC) displays the engine oil pressure as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the engine oil pressure. The engine oil pressure gage defaults to 0 psi (0 kPa) or below if:

• The PCM detects a malfunction in the engine oil pressure (EOP) sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
