3. Adjust:
throttle position sensor angle
a. Disconnect the throttle position sensor cou-
pler from the wire harness.
b. Connect the pocket tester (Ω
1k) to the
throttle position sensor coupler.

c. Measure the throttle position sensor maxi-
mum resistance.
d. Calculate the throttle position sensor maxi-
mum resistance when the throttle is fully
closed.
Throttle position sensor maximum
resistance (throttle is fully closed) =
Maximum resistance
(0.13 0.15)
Example
If the maximum resistance = 5 kΩ, then the
throttle position sensor’s maximum resistance
when the throttle is fully closed should be:
5 kΩ
(0.13 0.15) = 650 750 Ω
Lift the carburetor assembly slightly out of the
intake manifolds.

that the measured resistance is within the
specified range.
