WARNING: This page is about a different variant/trim than selected.
  1. READ AND RECORD DTCS AND ENVIRONMENTAL DATA - ERASE DTCS AND CHECK FOR THE DTC TO RETURN 
    NOTE:

    Low battery voltage can also cause excessive current draw. Make sure that the battery is fully charged and can pass a load test before continuing.

    1. With the scan tool, read DTCs in all Electronic Control Units (ECUs) and record on the repair order.
    2. For future reference, with the scan tool, run and save a vehicle Scan Report and all related recorded data.
    3. With the scan tool, erase all DTCs.
    4. Turn the ignition off for a minimum of 10.0 seconds.
    5. Turn the ignition on.
    6. Using the When Monitored and Set Conditions above and recorded data, operate the vehicle in the conditions that set the DTC.
    7. With the scan tool, read DTCs.

      Did the DTC return?

      Yes 

      • Go To  2

      No 

      NOTE:

      When this DTC is Active the engine speed, torque and vehicle speed are limited to a Limp in mode. An intermittent loss of power to the PCM without performing an ETC RELEARN procedure may cause this DTC to set.

  2. CHECK FOR OTHER DTCS 
    1. Refer to the recorded DTCs.

      Are DTCs P2100 or P2101 present?

      Yes 

      No 

      • Go To  3
  3. CHECK FOR ANY SERVICE BULLETINS OR PCM SOFTWARE UPDATES 
    1. Check for any applicable Service Bulletins or Flash updates related to the DTC.

      Are there any applicable Service Bulletins or Flash updates?

      Yes 

      No 

      • Go To  4
  4. CHECK THE THROTTLE BODY HARNESS CONNECTOR AND TERMINALS 
    1. Turn the ignition off.
    2. Check the Throttle Body harness connector for proper connection at the Throttle Body.
    3. Verify that the connector is completely plugged in and properly locked prior to disconnecting.
    4. Disconnect the Throttle Body harness connector and check for any pushed out, damaged or spread terminals.
      NOTE:

      An intermittent loss of a signal from one of the sensors may cause this DTC to set without setting a sensor fault.

      Were any issues found with the connector or terminals?

      Yes 

      • Repair the damaged terminal or properly connect and lock the Throttle Body harness connector and retest for DTCs.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  5
  5. ISOLATE AND LOAD TEST THE THROTTLE BODY (K447) MOTOR (+) CIRCUIT TO CHECK FOR HIGH RESISTANCE 
    NOTE:

    Note: Why load test a circuit?  A load test is used to determine if a circuit is capable of carrying the amperage needed to perform properly. The 3156 bulb in the load tool illustrated, is a simple but effective method of testing circuit functionality. A 3156 Bulb has approximately 6.0 Ohms of resistance when the bulb is powered  and draws approximately 2.0 amps. Read the CIRCUIT LOAD TESTING PROCEDURE for information on building a simple load test tool and for additional load testing information and alternative methods of load testing or voltage drop testing a circuit. Refer to CIRCUIT LOAD TESTING PROCEDURES .
