MID 036 - CID 0542 - FMI 04 Unfiltered Engine Oil Pressure short to ground
Conditions Which Generate This Code:
The signal to the Electronic Control Module (ECM) from the sensor for unfiltered engine oil pressure is less than 0.2 VDC for at least five seconds. Also, neither of the following diagnostic codes are active:
- 262 - 03 5 Volt Sensor DC Power Supply short to +batt
- 262 - 04 5 Volt Sensor DC Power Supply short to ground
System Response:
The ECM assumes the last valid value for unfiltered engine oil pressure. Monitoring for restriction of the oil filters is disabled.
The alarm output is activated. The code is logged.
Troubleshooting:
Test Step 1.
Results:
- OK - STOP
