Engine Oil Level Sensor Faults (12 05 02)

ENGINE OIL LEVEL SENSOR FAULTS

TECHNICAL SERVICE BULLETIN

SUBJECT

Engine Oil Level Sensor Faults 

SITUATION

Check control message indicates: 'Engine oil level below minimum', although the actual engine oil level is correct.

Fault code 283A - oil quality sensor - may also be stored in the Engine Control Module (DME/ECU).

CAUSE

There are two possible causes:

Isolated dirt particles inside of the oil level sensor may cause erroneous oil level messages in the check control display, which will not reoccur once faults stored in DME/ECU memory are deleted.

OR

The oil level sensor is defective.

CORRECTION

1. If the fault is "currently not present", delete the fault stored in the Engine Control Module (DME/ECU) memory.

   Do not replace the oil level sensor.

   No further repairs necessary.

2. If the fault is "currently present", run the engine for a few minutes at idle, delete the fault stored in the Engine Control Module (DME/ECU) memory and road test the vehicle.

   If the fault no longer occurs, do not replace the oil level sensor.

   NOTE: In the above scenarios the dirt particles that caused the faults in the oil level sensor have been flushed through the sensor during normal engine operation (if the fault does not reoccur) and should no longer cause erroneous low oil level readings. Do not perform an oil service since this will not remedy the situation.
3. If the fault is "currently present", run the engine for a few minutes at idle, delete the fault stored in the Engine Control Module (DME/ECU) memory and road test the vehicle.

   If the low oil level fault reoccurs, the oil level sensor must be replaced and the fault stored in the Engine Control Module (DME/ECU) memory deleted if necessary.

PROCEDURE

If replacement of the oil level sensor is necessary, refer to service information bulletin 11 01 02 for hold down nut torque specifications and nut torque sequence to avoid future oil level sensor leaks / damage.
