Symptom:
P1281-ENGINE IS COLD TOO LONG
When Monitored and Set Condition:
P1281-ENGINE IS COLD TOO LONG
When Monitored: The ignition key on, engine running.
Set Condition: The engine does not warm to 71ÉC (160ÉF) while driving (throttle off idle)
greater than 20 MPH for 20 minutes after start.
POSSIBLE CAUSES
COOLING SYSTEM PROBLEM
TEST ACTION APPLICABILITY
1NOTE: The best way to diagnose this DTC is to allow the vehicle to remain
outside overnight in order to have a completely cold soaked engine.
NOTE: Extremely cold outside ambient temperatures may cause this DTC to
set.
Verify that the coolant level is correct. If not, repair as necessary
NOTE: Ensure the ECT Sensor is operating correctly.
With the DRBIIIt, monitor the Engine Coolant Temperature value during the warm
up cycle. Make sure the transition of the temperature change is smooth.
Did the engine temperature reach a minimum of 71ÉC (160ÉF)?All
Ye s®Test Complete.
No®Refer to the Service Information for cooling system performance
diagnosis. The most probable cause is a Thermostat problem.
