(P0121) APPS 5-VOLT SUPPLY CIRCUIT (CONTINUED) 8. MEASURE RESISTANCE BETWEEN THE TP SENSOR 5-VOLT SUPPLY CIRCUIT AND SENSOR GROUND With the ignition off. Measure the resistance between the 5-Volt Supply circuit and all Sen- Is the resistance above 100 kohms for all measurements? Yes >> Go To 9 No >> Repair the 5-Volt Supply circuit for a short to the Sensor Ground circuit that measured below 100 kohms. Perform POWERTRAIN VERIFICATION TEST - VER 2. 9. MEASURE THE RESISTANCE BETWEEN GROUND AND THE APP SENSOR 5-VOLT SUPPLY CIRCUIT With the ignition off. Disconnect the PCM C4 harness connector. Note: Check connectors — Clean/repair as necessary. Is the resistance above 100 kohms? Yes >> Go To 10 No >> Repair the APP Sensor 5-Volt Supply circuit for a short to ground. Perform POWERTRAIN VERIFICATION TEST - VER 2.
