Symptom: P0123-THROTTLE POSITION SENSOR #1 HIGH When Monitored and Set Condition: P0123-THROTTLE POSITION SENSOR #1 HIGH When Monitored: With the ignition on. Battery voltage greater than 10 volts. Set Condition: Throttle Position Sensor voltage at the PCM is greater than 4.47 volts. One Trip Fault. POSSIBLE CAUSES THROTTLE POSITION SENSOR SWEEP INTERMITTENT CONDITION (K22) TP SIGNAL CIRCUIT SHORTED TO (K6) 5 VOLT SUPPLY CIRCUIT (K22) TP SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE TP SENSOR INTERNAL FAILURE (K22) TP SIGNAL CIRCUIT OPEN (K4) SENSOR GROUND CIRCUIT OPEN PCM TEST ACTION APPLICABILITY 1 NOTE: Ensure the throttle is fully closed and free from binding or carbon t, read the TP Sensor voltage. Is the voltage above 4.5 volts? All Yes → Go To 2 No → Go To 8 2 Turn the ignition off. All Yes → Repair the short to the (K6) 5 Volt Supply circuit in the (K22) TP Signal circuit. No → Go To 3 279 DRIVEABILITY - NGC |
