Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

THROTTLE BODY INSPECTION 

  1. Ignition on, engine not running.
  2. With a scan tool, select View DTCs. Record the related Freeze Frame data.
    NOTE:

    Diagnose any other DTCs before continuing.

    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:

    This DTC will set in extreme cold ambient temperatures when the PCM detects that the throttle plate is stuck. By the time the vehicle is serviced, the condition may be corrected.

  3. Turn the ignition off.
  4. Remove the air cleaner assembly.
  5. Check for any signs of a foreign material (ice or dirt) on the throttle plate or in the throttle bore that can cause the throttle plate to stick.

    Were any problems found?

    • Repair as necessary. If the throttle blade is frozen, allow the throttle body to thaw naturally in a warm location.
    • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST . .

    No 

    • Test complete.
