Throttle Position (TP) Sensor
NOTE:
TP sensor and fuel tank pressure sensor share a 5.0 volt reference voltage. A fuel tank pressure sensor failure that causes a short circuit will affect TP sensor output and set a TP sensor DTC.
Check TP sensor output voltage. See THROTTLE POSITION SENSOR SIGNAL VOLTAGE table. TP sensor output voltage should change smoothly as throttle position changes. Turn ignition off and disconnect TP sensor 3-pin connector. TP sensor resistance measured between terminals No. 1 and No. 3 should be 3200-4800 ohms. Replace TP sensor if output voltage or resistance is not as specified.
THROTTLE POSITION SENSOR VOLTAGE
| Position | Volts |
|---|---|
| Idle | 0.6 |
| Maximum Throttle | 4.5 |
