    1. Measure the resistance between the (K122) TPS Signal 2 circuit and the (K126) ETC Motor (-) in the Throttle Body harness connector.

      Is the resistance above 10k Ohms?

      Yes 

      • Go To  7

      No 

      • Repair the (K122) TPS Signal 2 circuit for a short to the (K126) ETC Motor (-) circuit.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  7. CHECK THE (K122) TPS SIGNAL 2 CIRCUIT FOR AN OPEN/HIGH RESISTANCE 
    1. Turn the ignition off.
      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.

    2. Connect the (special tool #10436, Adapter, GPEC Diagnostic).
