Engine Oil Pressure Gauge

The IPC displays the engine oil pressure as determined by the ECM. The ECM monitors the engine oil pressure sensor. The IPC receives a serial data message from the ECM indicating the engine oil pressure. The engine oil pressure gauge defaults to 0 kPa (0 psi) or below if:

• The ECM detects a malfunction in the engine oil pressure sensor signal circuit.
• The IPC detects a loss of serial data communication with the ECM.
