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.
