Engine Oil Pressure Gauge (if equipped)
WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
The Instrument Panel Cluster Control Module displays the engine oil pressure as determined by the ECM. The ECM monitors the engine oil pressure sensor. The Instrument Panel Cluster Control Module 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 Instrument Panel Cluster Control Module detects a loss of serial data communication with the ECM.
