  Yes
  - Go To 4
  No
  - Repair the (K122) Throttle Position Sensor Signal 2 circuit for an open or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK FOR HIGH RESISTANCE IN THE (K922) THROTTLE POSITION SENSOR GROUND CIRCUIT
1. Measure the resistance of the (K922) Throttle Position Sensor Ground circuit between the Throttle Body harness connector and the GPEC Adaptor.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Go To 5
  No
  - Repair the (K922) Throttle Position Sensor Ground circuit for an open or high resistance.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
THROTTLE BODY
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. Inspect the Throttle Body for any condition that would result in an incorrect signal, such as damage or contamination.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Replace the Throttle Body in accordance with the service information. Refer to THROTTLE BODY, REMOVAL .
  - Go To 6
POWERTRAIN CONTROL MODULE (PCM)
1. With the scan tool, erase the DTCs.
2. Start the engine and Test drive the vehicle.
3. With the scan tool, view the DTCs.
  Did the DTC return?
  
  Yes
  - Replace and program the Powertrain Control Module (PCM) in accordance with the service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Repair is complete.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
