Throttle Position Sensor/Switch: Adjustments
THROTTLE POSITION SENSOR ADJUSTMENTNOTE: Before adjusting the throttle position sensor complete the basic idle speed adjustment.
1. Disconnect the throttle position sensor adjustment.
2. Using a jumper wire connect a voltmeter between terminal 1 (sensor ground) and terminal 2 (idle switch) of the throttle position sensor connector.
3. Insert a 0.65 mm (0.0256 in) thick feeler gauge between the fixed speed adjusting screw and the throttle lever.
4. Loosen the throttle position sensor mounting bolts and turn the throttle position sensor body fully counterclockwise.
5. In this position check that there is continuity between terminals 1 and 2.
6. Slowly turn the throttle position sensor clockwise until you find a point at which there is no continuity between terminals 1 and 2. Then tighten the throttle position sensor mounting bolt securely.
7. Connect the throttle position sensor connector.
8. Connect the scan tool to the data link connector in the fuse box.
9. If the scan tool is not used connect a voltmeter between terminal 1 (sensor ground) and terminal 3 (sensor output) of the throttle position sensor connector using a pin.
NOTE: Do not disconnect the throttle position sensor. use a digital voltmeter to obtain an accurate value.
10. Turn the ignition switch ON.
NOTE: Do not start the engine.
11. Check the throttle position sensor output value.
Standard Value: 400-1000 m Volts
12. If the voltage is out of specification check the throttle position sensor and associated harnesses.
13. Remove the feeler gauge.
14. Turn the ignition switch OFF.
