Throttle Position Sensor (TPS): Testing

1. Disconnect the throttle position sensor connector.
2. Measure the resistance between terminal 1 (ground) and terminal 4 (sensor power).

   Standard value : 3.5~6.5 kΩ

3. Measure the resistance between terminal 1 (ground) and terminal 2 (sensor output).
4. Operate the throttle valve slowly from the idle position to full open position and check that the resistance changes smoothly in proportion with the throttle valve opening angle.
5. If the resistance is out of specification, or fails to change smoothly, replace the throttle position sensor.

Tightening torque

TPS: 1.5~2.5 N-m (15~25 kg-cm, 1.1~1.8 lb-ft)
