8. (K922) TP SENSOR GROUND CIRCUIT OPEN OR HIGH RESISTANCE Measure the resistance of the (K922) TP Sensor Ground circuit Is the resistance below 5.0 ohms? Yes >> Go to 9 No >> Repair the (K922) TP Sensor Ground circuit for an open cir- cuit or high resistance. Perform the PCM Verification Test Ver. 1 (Refer to 9 - 9. THROTTLE BODY Turn the ignition off. Connect the Powertrain Control Module (PCM) connector. Connect a jumper wire between the (K922) TP Sensor Ground circuit Turn the ignition on. With the scan tool, read the TP Signal 2 circuit voltage. Is the voltage below 1.0 volt with the jumper wire in place? Yes >> Replace the Throttle Body in accordance with the Service Information. Perform the PCM Verification Test Ver. 1 (Refer to 9 - No >> Go to 10 10. POWERTRAIN CONTROL MODULE (PCM) Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Throttle Body and Look for any chafed, pierced, pinched, or partially broken wires. Look for broken, bent, pushed out or corroded terminals. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors. Look for the data to change or for the DTC to reset during the wiggle test. Refer to any Technical Service Bulletins that may apply. Were any problems found? Yes >> Repair as necessary. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). No >> Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information. Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 219 |
