Throttle Position Sensor: Adjustments

Throttle Sensor Adjustment

Throttle Position Sensor Circuit

1.

Remove throttle sensor connector.

2.

Insert a thickness gauge (0.35mm, 0.0138in) between throttle body stopper screw and stopper (portion "G").  Resistance between terminals "3" and
"4" should be 5k ohms maximum.

4.

Replace first thickness gauge with a second (0.75mm, 0.0295in  Resistance between terminals "3" and "4" should be 1M ohms minimum.

4.

Resistance between terminals "1" and "4" should be 3-7k ohms.

5.

Measure resistance between terminals "2" and "4".  It should be 4.2-15k ohms with throttle fully closed and 0.1-11k ohms with throttle fully
opened.

6.

Ensure that resistance changes smoothly between fully opened and fully closed throttle positions.

7.

If resistance is out of specification, replace sensor.
