a. After performing the full open angle of the
sub-throttle position sensor, turn the nut of
the worm shaft clockwise, measure the
dimension of "b" section with a micrometer
caliper or other device and adjust so that
the dimension is in a range from 8.1 to 8.5
mm (0.32 to 0.33 in).

a. Connect the sub-throttle position sensor
coupler to the wire harness.
b. Connect the digital circuit tester to the sub-
throttle position sensor.
• Positive tester probe

c. Move the sub-throttle position sensor to
adjust to be in the specified range.
Sub-throttle
voltage
0.97–1.07 V
d. After adjusting the sub-throttle position
sensor voltage, tighten the sub-throttle
position sensor screws.
NOTE:
• After setting up the sub-throttle position sen-
sor, check that the sub-throttle position sen-
sor output voltage is 0.4 V or more with the
nut of worm shaft turned to the full close side
until it stops.
• When the sub-throttle position sensor output
voltage is 0.4 V or more, check that the sub-
throttle position sensor output voltage is 4.6
V or less with the nut of worm shaft turned to
the full open side until it stops.
