For the Engine circuit diagram (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).
For a complete wiring diagram Refer to Section 8W.
•
When Monitored:
Ignition on.
•
Set Condition:
The PCM recognizes the Throttle plate is stuck during extremely cold Ambient Temperature operation. The
throttle plate goes through a de-icing procedure. If the throttle blade still doesn’t move this fault sets. The MIL
will not illuminate. The vehicle will be in Limp home condition, limiting rpm and vehicle speed.
Possible Causes
THROTTLE PLATE FROZEN
Diagnostic Test
1.
THROTTLE BODY INSPECTION
Ignition on, engine not running.
With a scan tool, read DTCs and record the related Freeze Frame data.
NOTE: This DTC sets in extreme cold Ambient Temperatures with the throttle plate stuck by the time the
vehicle gets to the dealership the condition may be corrected.
NOTE: Diagnose any other DTCs that may also be set before continuing.
Turn the ignition off.
Remove the Air Cleaner Assembly from the Throttle Body.
Check for any signs of a foreign material (ice or dirt) on the Throttle Plate or in the bore causing the Throttle Plate
to stick.
Is the throttle blade still stuck because it is frozen?
Yes
>> Allow the Throttle Body to thaw naturally in a room temperature climate.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No
>> Test Complete.
