Throttle Position Sensor: Testing and Inspection

Throttle Position Sensor:

1. Disconnect the throttle position sensor connector.
2. Measure the resistance between the throttle position sensor side connector terminal 1 and terminal 3.
Standard value: 3.5k to 6.5k ohms
3. Measure the resistance between the throttle position sensor side connector terminal 2 and terminal 3. Open throttle valve slowly open until fully open from the idle position
- Resistance should change smoothly in proportion to the opening angle of the throttle valve.
4. If the resistance is outside the standard value, or if it doesn't change smoothly, replace the throttle position sensor.
