Throttle Body: Adjustments

Basic Throttle Setting (not ETS)




1 Remove the hose.

2 Slightly back off the bolts securing the throttle position switch.

3 Turn the adjusting screw to a position where it touches the stop (throttle fully closed)

4 Screw in the adjusting screw about another 1/3 turn and secure it with the locknut. This will give a clearance of 0.05 mm (0.002 in) between the throttle butterfly and throttle body.

5 Check that the length of the throttle cable does not prevent the butterfly from reaching the closed throttle position and that there is no free play at the accelerator.

6 Check that the throttle opens fully when the accelerator is in the wide open throttle position.

7 Adjust the throttle position switch. It should be closed in the idle speed position. Tighten the bolts. When the throttle leaves the idle speed position a clicking sound should be heard from the switch.
