Diagnostic Test

  1. ACTIVE DTC 
    NOTE: When this DTC is Active the engine speed, torque, and vehicle speed are limited to a Limp in mode.
    NOTE: If the P2118 is intermittent, it is possible that the controller is overheating in extreme hot temperatures, and this is considered a normal protection operation. No repair is necessary.
    NOTE: If P2072 is also set, this indicates that the cold weather ice blockage routine has run. No repair action is required.
    1. Ignition on, engine not running.
    2. With a scan tool, select View DTCs.
    3. Look closely at the temperatures at which this DTC set.

      Is the DTC Active at this time?

      Yes 

      • Go to step  2

      No 

  2. THROTTLE PLATE INSPECTION 
    1. Turn the ignition off.
    2. Remove the Air Cleaner Assembly from the Throttle Body.
    3. 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.

      Were any signs of foreign material or scoring of the throttle plate or bore found?

      Yes 

      No 

      • Go to step  3
  3. (K124) ETC MOTOR (+) CIRCUIT SHORTED TO VOLTAGE

    1. Turn the ignition off.
    2. Disconnect the Throttle Body harness connector.
    3. Disconnect the C2 PCM harness connector.
    4. Ignition on, engine not running.
      CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install PCM Pinout Box 8815 to perform diagnosis.
    5. Measure the voltage on the (K124) ETC Motor (+) circuit at the appropriate terminal of special tool #8815.

      Is there any voltage present?

      Yes 

      No 

      • Go to step  4
  4. (K126) ETC MOTOR (-) CIRCUIT SHORTED TO VOLTAGE 
    Fig 2: Checking ETC Motor Circuit

    1. Measure the voltage on the (K126) ETC Motor (-) circuit at the appropriate terminal of special tool #8815.

      Is there any voltage present?

      Yes 

      No 

      • Go to step  5
  5. (K124) ETC MOTOR (+) CIRCUIT SHORTED TO THE (K126) ETC MOTOR (-) CIRCUIT 
    Fig 3: Checking ETC Motor Circuit

    1. Turn the ignition off.
    2. Measure the resistance between the (K124) ETC Motor (+) circuit and the (K126) ETC Motor (-) circuit at the appropriate terminals of special tool #8815.

      Is the resistance below 100 ohms?

      Yes 

      No 

      • Go to step  6
  6. (K124) ETC MOTOR (+) CIRCUIT OPEN

    1. Measure the resistance of the (K124) ETC Motor (+) circuit from the Throttle Body harness connector to the appropriate terminal of special tool #8815.

      Is the resistance below 5.0 ohms?

      Yes 

      • Go to step  7

      No 

  7. (K124) ETC MOTOR (+) CIRCUIT SHORTED TO GROUND 
    Fig 5: Checking ETC Motor (+) Circuit

    1. Measure the resistance between ground and the (K124) ETC Motor (+) circuit between the appropriate terminals of special tool #8815.

      Is the resistance below 100 ohms?

      Yes 

      No 

      • Go to step  8
  8. (K126) ETC MOTOR (-) CIRCUIT OPEN 
    Fig 6: Checking ETC Motor (-) Circuit
    GC0097651Courtesy of CHRYSLER LLC
    1. Measure the resistance of the (K126) ETC Motor (-) circuit from the Throttle Body harness connector to the appropriate terminal of special tool #8815.

      Is the resistance below 5.0 ohms?

      Yes 

      • Go to step  9

      No 

  9. (K126) ETC MOTOR (-) CIRCUIT SHORTED TO GROUND 
    Fig 7: Checking ETC Motor Circuit
    GC0102070Courtesy of CHRYSLER LLC
    1. Measure the resistance between ground and the (K126) ETC Motor (-) circuit between the appropriate terminals of special tool #8815.

      Is the resistance below 100 ohms?

      Yes 

      No 

      • Go to step  10
  10. ETC MOTOR 
    Fig 8: Checking ETC Motor Circuit
    GC0102066Courtesy of CHRYSLER LLC
    NOTE: Take the following measurement using special tool #8815 to avoid possible damage to the Throttle Body harness connector.
    1. Connect the Throttle Body harness connector.
    2. Measure the resistance of the ETC Motor between the (K124) ETC Motor (+) circuit and the (K126) ETC Motor (-) circuit at the appropriate terminals of special tool #8815.

      Is the resistance between 2.5 and 25 ohms at closed throttle?

      Yes 

      • Go to step  11

      No 

      • Verify that there is good pin to terminal contact in the Throttle Body and the Powertrain Control Module connectors. If OK, replace the Throttle Body Assembly. Disconnect the Battery when replacing the Throttle Body Assembly. After installation is complete, use a scan tool and select the ETC RELEARN function.
      • Perform the PCM Verification Test. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure
  11. POWERTRAIN CONTROL MODULE (PCM) 
    1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Throttle Body and the Powertrain Control Module (PCM).
    2. Look for any chafed, pierced, pinched, or partially broken wires.
    3. Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the Throttle Body and the Powertrain Control Module connectors.
    4. Refer to any Technical Service Bulletins that may apply.

      Were there any problems found?

      Yes 

      No
