2006 DODGE RAM SRT-10 climate control

P2072-ELECTRONIC THROTTLE CONTROL SYSTEM - ICE BLOCKAGE
For a complete wiring diagramRefer 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 willbe 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 throttleplatestuckbythetimethe
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 Plateor in the bore causing the Throttle Plate
to stick.

Allow the Throttle Body to thaw naturally in a room temperature climate.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

12.RUN THE ACTUATOR DTC DETECTION TEST
Reconnect the A/C Heater Control C1 harness connector.
Turn the ignition on.
With the scan tool in HVAC, select System Tests and then select Actuator DTCDetection. When the test is com-
plete, select View DTCs.
Does the scan tool only display: B105F–CLIMATE CONTROL MOTOR(S) COMMON 1 CONTROL CIRCUIT
LOW?
Ye s>>
Replace the A/C Heater Control in accordance with the Service Information.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES - STANDARD PROCEDURE).
No, Other DTC(s) Displayed
Diagnose and repair the other DTC(s). If multiple DTCs are present, beginning with the passenger blend
door, diagnose and repair all short high DTCs and then all short low DTCs. Refer to the Table of Con-
tents in this Section for a complete list of HVAC related symptoms.
No, And No DTCs Displayed
Using the wiring diagram as a guide, inspect the wiring and connectors for conditions causing an inter-
mittent short. Repair as necessary.
