With SST-New Generation Star Tester

ADJUSTMENT

CAUTION: The throttle position sensor is adjusted at the factory before shipment. Unnecessarily 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.

Closed throttle position switch
1. Verify that the throttle valve is 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 Nm (14-20 in.lb.)

6. If not adjusted, replace the throttle position sensor.
