Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.
  1. ACTIVE DTC 
    NOTE:

    Diagnose and repair any Throttle Body circuit, system voltage, or sensor supply voltage DTCs before continuing with this test.

    1. Start the engine and allow it to reach operating temperature.
      WARNING:

      When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.

    2. With the scan tool select View DTCs.
      NOTE:

      If the DTC does not reset it may be necessary to test drive the vehicle.

      Is the DTC Active at this time?

      Yes 

      • Go To  2.

      No 

      • Go To  7.
  2. THROTTLE POSITION SENSOR 
    1. Turn the ignition off.
    2. Disconnect the Throttle Body Assembly harness connector.
    3. Ignition on, engine not running.
    4. With the scan tool monitor the TP Sensor No. 2 voltage.
      NOTE:

      The sensor voltage should be approximately 0.0 volts (plus or minus.1 volt) with the connector disconnected.

      Does the scan tool display the voltage as described above?

      Yes 

      • Verify that there is good pin to terminal contact at the Throttle Body and the Powertrain Control Module connectors. Replace the Throttle Body Assembly if no problems were found in the connectors. 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 POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  3.
  3. (K122) TP SENSOR NO. 2 SIGNAL CIRCUIT SHORTED TO VOLTAGE

    1. Turn the ignition off.
    2. Disconnect the C2 PCM harness connector.
    3. Ignition on, engine not running.
    4. Measure the voltage on the (K122) TP Sensor No. 2 Signal circuit at the Throttle Body harness connector.

      Is there any voltage present?

      Yes 

      • Repair the short to voltage in the (K122) TP Sensor No. 2 Signal circuit.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  4.
  4. (K122) TP SENSOR NO. 2 SIGNAL CIRCUIT SHORTED TO (F855) 5-VOLT SUPPLY CIRCUIT 
    Fig 2: Measuring Resistance Between (K122) TP Sensor No. 2 Signal Circuit And (F855) 5-volt Supply Circuit AT Throttle Body Harness Connector

    1. Measure the resistance between the (K122) TP Sensor No. 2 Signal circuit and the (F855) 5-volt Supply circuit at the Throttle Body harness connector.

      Is the resistance below 100 ohms?

      Yes 

      • Repair the short between the (K122) TP Sensor No. 2 Signal circuit and the (F855) 5-volt Supply circuit.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .

      No 

      • Go To  5.
  5. (K922) TP SENSOR RETURN CIRCUIT OPEN 
    Fig 3: Measuring Resistance Of (K922) TP Sensor Return Circuit From Throttle Body Harness Connector To Appropriate Terminal Of Special Tool #8815

    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 the PCM Pinout Box (special tool #8815A, Kit, NGC, 38 Position) to perform diagnosis.

    1. Measure the resistance of the (K922) TP Sensor Return circuit from the Throttle Body harness connector to the appropriate terminal of special tool (special tool #8815A, Kit, NGC, 38 Position).

      Is the resistance below 5.0 ohms?

      Yes 

      • Go To  6.

      No 

  6. 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 Control Module connectors.
    4. Refer to any Technical Service Bulletins that may apply.

      Were there any problems found?

      Yes 

      No 

      • Replace and program the Powertrain Control Module per Service Information.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  7. THROTTLE FOLLOWER TEST 
    1. With the scan tool, perform the ETC Throttle Follower Test.
    2. Monitor the TP Sensor No. 2 voltage while slowly pressing the Throttle pedal down.

      Is there a smooth voltage change from approximately 4.3 volts down to approximately 0.7 of a volt?

      Yes 

      No 

      • Verify that there is good pin to terminal contact at the Throttle Body and the Powertrain Control Module connectors. Replace the Throttle Body Assembly if no problems were found in the connectors. 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 POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
