DESCRIPTION:
This code sets when the motor control module (MCM) detects engine oil temperature above normal range.
MONITORED PARAMETER:
Engine oil temperature sensor.
TYPICAL ENABLING CONDITIONS:
Always enabled
MONITOR SEQUENCE:
None
EXECUTION FREQUENCY:
Always enabled
TYPICAL DURATION:
Two seconds
DASH LAMPS:
CEL
ENGINE REACTION:
None
VERIFICATION:
Run the engine at 1200 rpm until coolant temperature reaches 49°C (120°F).
PROBABLE CAUSES:
1. Low oil level.
2. Cooling system leaks.
3. Engine fan failure.
4. Coolant thermostate failure.
5. Engine oil temperature sensor failure.
6. Engine oil temperature sensor connector/harness.
