      Yes 

      • Go To  7

      No 

      • Repair the short between the (K122) TPS Signal 2 circuit and the (K448) ETC Motor (-) circuit.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  7. CHECK THE (K122) TPS SIGNAL 2 CIRCUIT FOR AN OPEN/HIGH RESISTANCE 
    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 GPEC Diagnostic Adaptor to perform the diagnosis.

    1. Connect the (special tool #10436, Adapter, GPEC Diagnostic).
    2. Measure the resistance of the (K122) TPS Signal 2 circuit between the Throttle Body harness connector and the GPEC Adaptor.

    5. With a scan tool, read the Throttle Body voltage.
      NOTE:

      The sensor voltage should be approximately 0.0 volts (plus or minus.1 volts) with the jumper in place.

      Does the scan tool display the voltage as described above?

      Yes 

      • Replace the Throttle Body in accordance with the service information.
      • Verify that there is good pin to terminal contact in the Throttle Body and Powertrain Control Module connectors. If OK, disconnect the Battery when replacing the Throttle Body Assembly. Replace the Throttle Body Assembly. Refer to THROTTLE BODY, REMOVAL . After installation is complete, using a scan tool select the ETC RELEARN function.

      No 

      • Go To  10
  10. 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.
    4. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
    5. Look for the data to change or for the DTC to reset during the wiggle test.
    6. Perform any Technical Service Bulletins that may apply.

      Were any problems found?

      Yes 

      • Repair as necessary.
