Throttle Position Sensor: Adjustments

1. Disconnect the throttle position sensor connector.




2. Use jumper wires to connect an ohmmeter between terminal (2) (closed throttle position switch) and terminal (1) (sensor ground) of the throttle position sensor.




3. Insert a feeler gauge with a thickness of 0.65 mm (0.0256 in.) between the fixed SAS and throttle lever.




4. Loosen the throttle position sensor mounting bolts and turn the throttle position sensor body fully clockwise. In this condition, check for continuity between terminal (1) and terminal (2).




5. Slowly turn the throttle position sensor counterclockwise until you find a point at which there is no continuity between terminal (1) and terminal (2). Then, tighten the throttle position sensor mounting bolt securely
6. Connect the throttle position sensor connector.

Data Link Connector:

7. Connect the scan tool to the data link connector (white) .




If not using the scan tool, proceed as follows:
- Disconnect the throttle position sensor connectors and connect the special tool. Test Harness Set, between the disconnected connectors:
- Connect a digital voltmeter between throttle position sensor terminal (3) (sensor output) and terminal (1) (sensor ground) .

8. Turn the ignition switch to ON (but do not start the engine) . (11) Check the throttle position sensor output voltage.

Standard value: 400-1,000 mV

9. If the voltage is outside the standard value, check the throttle position sensor and associated harnesses.
10. Remove the feeler gauge.
11. Turn the ignition switch to OFF.
