Oil Pressure

The IPC obtains oil pressure data from the PCM on the serial data line. The PCM is responsible for processing this data and sending the correct values to the IPC for display. The IPC will display the LOW OIL PRESSURE message and the CHECK GAGES indicator when the IPC receives low oil pressure data from the PCM. If the IPC cannot receive proper oil pressure data from the PCM (due to a communication or sensor malfunction), the IPC will command the oil pressure gauge to the lowest possible setting.
