a. Disconnect the throttle position sensor
coupler from the wire harness.
b. Connect the pocket tester (
Ω ×
1k) to the
throttle position sensor coupler.
c. Measure the throttle position sensor
maximum resistance.
d. Calculate the throttle position sensor
maximum resistance when the throttle is
fully closed.
Example:
If the maximum resistance = 5 k
Ω
, then the
throttle position sensor’s maximum resis-
tance when the throttle is fully closed
should be:
5 k
Ω ×
(0.13 ~ 0.15) = 650 ~ 750
Ω
Lift the carburetor assembly slightly out of
the intake manifolds.
Loosen the throttle position sensor screws

.
Connect the pocket tester (
Ω ×
100) to the
throttle position sensor.
e. Adjust the throttle position sensor angle
so that the measured resistance is within
the specified range.
After adjusting the throttle position sensor
angle, tighten the throttle position sensor
screws.
