MID 036 - CID 0100 - FMI 03 Engine Oil Pressure open/short to +batt
Conditions Which Generate This Code:
The signal from the filtered oil pressure sensor to the Electronic Control Module (ECM) is greater than 4.8 VDC for at least five seconds.
Additionally, 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 the engine oil pressure. The monitoring of the oil pressure is disabled. This disables the engine protection for low oil pressure and excessive oil pressure.
The fuel is shut off. The shutdown output is activated. The code is logged.
Possible Performance Effect:
Since the engine protection is disabled, the engine is shut down.
Troubleshooting:
This condition indicates an open circuit or a short circuit to a positive voltage source.
Test Step 1.
Results:
- OK - STOP
