f. While slowly opening the throttle, check that
the throttle position sensor resistance is with-
in the specified range.
The resistance does not change or it
changes abruptly ! Replace the throttle
position sensor.
The slot is worn or broken ! Replace the
throttle position sensor.
Check mainly that the resistance changes grad-
ually when turning the throttle, since the read-
ings (from closed to wide-open throttle) may dif-
fer slightly from those specified.

2. Adjust:
Sthrottle position sensor angle
a. Connect the throttle position sensor coupler
to the wire harness.
b. Connect the digital circuit tester to the throttle
position sensor.

c. Measure the throttle position sensor voltage.
d. Adjust the throttle position sensor angle so
the measured voltage is within the specified
range.
Throttle position sensor voltage
0.63 X 0.73 V
(yellow – blue)
g. After adjusting the throttle position sensor
angle, tighten the throttle position sensor
screws.
