Symptom:
P0123-THROTTLE POSITION SENSOR VOLTAGE HIGH
When Monitored and Set Condition:
P0123-THROTTLE POSITION SENSOR VOLTAGE 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 4.5 volts for
0.7 seconds.
THROTTLE POSITION SENSOR SWEEP
(K22) TP SENSOR SIGNAL CIRCUIT SHORTED TO (K6) 5-VOLT SUPPLY CIRCUIT
(K22) TP SENSOR SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE
TP SENSOR INTERNAL FAILURE
INTERMITTENT CONDITION
PCM
TEST
1 NOTE: Ensure the throttle is fully closed and free from binding or carbon
build up.
Start the engine.
With the DRBIII , read the TP Sensor voltage.
Is the voltage above 4.5 volts?
Yes → Go To 2
→ Go To 6
No
2 Turn the ignition off.
Disconnect the TP Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance between the (K22) TP Sensor Signal circuit and the (K6)
5-volt Supply circuit in the TP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short between (K6) 5-volt Supply circuit and the (K22)
→ Go To 3
No
