THROTTLE BODY INSPECTION 

1. Ignition on, engine not running.
2. With the scan tool, select View 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:

   P2110 will set with P2072. P2118 may also set and the customer will experience a Limp-in condition. If either of these two faults are set, it indicates that the ice blockage software has run and no repair is necessary.

   NOTE:

   Diagnose any other DTCs that may also be set before continuing.

3. Turn the ignition off.
4. Remove the Air Cleaner Assembly from the Throttle Body.
