Throttle Position Sensor: Testing and Inspection

COMPONENT INSPECTION
1. Start engine and warm it up sufficiently.
2. Turn ignition switch "OFF".
3. Disconnect throttle position sensor harness connector.




4. Make sure that resistance between terminals (2) and (3) changes when opening throttle valve manually.

Throttle valve conditions / Resistance at 25°C (77°F)
Completely closed / Approximately 0.5 K Ohms
Partially open / 0.5 - 4.0 K Ohms
Completely open / Approximately 4.0 K Ohms

If NG, replace throttle position sensor.
To adjust throttle position sensor, perform "BASIC INSPECTION".
