Throttle Plate Adjustment
Adjust spindle until end projects 22 +/- 0.5 mm beyond throttle housing as illustrated.
Note:
Specified maximum dimension of 22.5 mm must not be exceeded, otherwise spindle may bottom against throttle switch.
Tighten plate retaining screws (Torque: 0.6 +/- 0.1 Nm = 5 +/- 1 in.lb).
Turn adjusting screw until it is just in contact with lever. Screw in a further quarter turn.
Tighten locknut while holding adjusting screw.
1.3 ADJUSTMENT OF THROTTLE SWITCH
Install throttle switch without tightening screws.
(Two makes of throttle switch - BOSCH and VDO - are used. The manufacturer's name is shown on the rounded section of the cover. Proceed as follows
depending on which make of switch is installed).
TPS Switch
Turn switch clockwise.
BOSCH:
Turn switch counterclockwise until "click" is heard. Continue until stop is reached but no further. Since throttle must not begin to open, plate may be
held closed with finger. Hold switch in this position and tighten screws (torque: 1.6 +/- 0.4 Nm = 14 +/- 4 in.lb).
VDO:
Place 0.25 mm feeler gauge between throttle lever and adjusting screw. Turn switch slowly counterclockwise until "click" is heard. Hold switch in this
position and tighten mounting screws (torque: 1.6 +/- 0.4 Nm = 14 +/- 4 in.lb). Apply medium grade locking fluid to screws before tightening.
Recheck operation:
