Check Engine Oil Pressure

The Check Eng Oil Pressure message input to the IPC will be a discrete wire from the oil pressure sensor. The oil pressure sensor output signal must be a variable resistance to ground, as measured at the IPC connector. The conditions for asserting the Check Eng Oil Pressure message in the message center display are described below.
- The CHECK ENG OIL PRESSURE message will be added to the display when the input resistance is less than five ohms and the engine has been running for more than 5 seconds.
- The CHECK ENG OIL PRESSURE message will be removed from the display if the input resistance increases to 12 ohms.
