Throttle Position Switch: Adjustments

Remove link rod from throttle control pulley:
- Loosen throttle control switch screws (inhex 3 mm).

- Turn switch clockwise.





Adjust throttle valve:
- Loosen adjustment screw lock nut (8 mm wrench).

- Loosen adjustment screw until throttle valve completely closes.

- Tighten screw until it just touches throttle valve lever.

- Tighten screw additionally 1/4 turn.

- Tighten lock nut.

- Check that throttle valve moves easily and does not bind.





Adjust throttle valve switch:
- Turn switch counter-clockwise to stop, but not so far that throttle valve begins to move.

- Tighten screws.

-. Check adjustment.

- A "click" (idle switch opens) should be heard immediately when throttle valve moves.





Check throttle control pulley:
- Adjust throttle cable.

- Pulley should move easily without binding.

- Cable should be stretched but should not influence pulley position.

- Pulley should touch idle stop.

- Depress accelerator pedal to floor and check that throttle control pulley touches full throttle stop.





Check / adjust kick-down cable (automatic transmission):
- Depress accelerator pedal to floor.

CAUTION: Do not operate throttle control by hand as incorrect adjustment can result.

- At full throttle distance from cable sheath to clip should be 5O.4 - 52.6 mm (1.98 - 2.O7 in).





Connect and adjust link rod:
- Position a 1 mm thick feeler gauge between throttle control pulley and idle stop.

- Adjust link rod so clearance between throttle valve lever and adjustment screw is 0.1 mm (0.004 in).





Check idle speed:
