System Schematic For the Engine Oil Pressure SensorThis diagnostic code is for the pressure sensor (engine oil).The EMCP II monitors the engine oil pressure in order to protect the engine from a problem with the oil pressure. The oil pressure sensor is mounted on an oil gallery of the engine. The exact location of the engine oil pressure sensor varies depending on the engine model.The sensor is powered by an 8 volt sensor supply from the GSC. The oil pressure signal is a pulse width modulated signal. The base frequency of the signal is 500 150 Hz. As pressure changes, the duty cycle of the signal varies from 10 to 95 percent.
0 kPa (0 psi) is approximately 13% of the duty cycle. The voltage will be approximately 1.0 DCV.
690 kPa (100 psi) is approximately 85% of the duty cycle.System Response:Note: The GSC is usually programmed to treat a problem with the oil pressure sensor as an alarm fault. The factory default for 004 is 0. The GSC is programmed to shutdown for a problem with the pressure sensor. Pressing the diagnostic key is not necessary in order to view the CID 0100 FMI 04. 004 is equal to 1 for a shutdown fault. The upper display automatically shows the CID 0100 FMI 04.Note: Diagnostic codes are created when the harness connector is disconnected from the GSC during the troubleshooting procedures. Clear these created diagnostic codes after the particular problem is corrected. The possible cause of a CID 0100 FMI 04 is listed below:
A short to ground of the sensor signal.Begin performing these procedures only when CID 100 FMI 4 is showing and the "DIAG" indicator is FLASHING on the upper display. The diagnostic code is active. The GSC treats a CID 0100 FMI 04 as an alarm fault. Active alarm faults are shown on the display when the "Alarm Codes" key is pressed. The engine control switch (ECS) must not be in the OFF/RESET position. For an inactive diagnostic code, the problem may be intermittent. To troubleshoot an inactive diagnostic code, use the preceding system schematic and see Testing And Adjusting, "Electrical Connector - Inspect". Clear the diagnostic code from the fault log after troubleshooting is complete.If a CID 0269 for the sensor supply is active, correct the diagnostic code prior to proceeding with this procedure.Test Step 1. CHECK THE GSC AND THE HARNESS.
Make sure that CID 0100 FMI 04 is showing on the display.
Turn the ECS to the OFF/RESET position.
Disconnect the sensor from the engine harness. The sensor remains fastened to the engine.
Turn the ECS to the STOP position.
Press the "Alarm Codes" key.
Check if the CID 0100 FMI 04 is not showing. Check if the CID 0100 FMI 03 is now showing. Expected Result:CID 0100 FMI 04 is not showing. CID 0100 FMI 03 is now showing. CID 0100 FMI 03 is now active.Results:
OK - CID 0100 FMI 04 is not showing. CID 0100 FMI 03 is now showing. CID 0100
