Throttle Position Sensor: Adjustments

CAUTION:
- The throttle position sensor is adjusted at the factory before shipment Unnecessary adjustment will negatively effect the engine performance.
- Adjusting the throttle position sensor by using the throttle adjusting screw (TAS) will negatively effect the engine performance.




1. Verify that the throttle valve is at the closed throttle position.
2. Disconnect the throttle position sensor connector.
3. Loosen the attaching screws.




4. insert a feeler gauge between the throttle adjusting screw (TAS) and the throttle lever. Adjust the continuity between the closed throttle position switch terminals C and D by using an ohmmeter.




5. Tighten the attaching screws.

Tightening torque
1.6-2.3 N.m {16-24 kgf.cm, 14-20 in.lbf}




6. Connect the SSTs (NGS tester) to the data link connector-2 located under the driver side dashboard.
7. Verify that the throttle valve is at the closed throttle position.
8. Turn the ignition switch to ON.




9. Select the "PID/DATA MONITOR AND RECORD" function of the NGS tester display.
10. Select "TP V" on the NGS tester display. NGS tester measures and shows the voltage.

Specification
Closed throttle position: 0.1-1.1 V
Wide open throttle: 2.8-4.5 V
(Verify that the voltage increase Is directly proportioned to the throttle valve opening angle.)

11. If not as specified, replace the throttle position sensor.
