CHECKING AND ADJUSTING THE THROTTLE
POSITION SENSOR
Before adjusting the throttle position sensor, the
engine idling speed should be properly ad-
justed.
1. Check:
S throttle position sensor
(installed on the carburetor)
a. Disconnect the throttle position sensor cou-
pler.
b. Connect the pocket tester (Ω 1k) to the
throttle position sensor.

c. Measure the throttle position sensor maxi-
mum resistance.
Out of specification  Replace the throttle
position sensor.

resistance
4.0 X 6.0 kΩ at 20_C
(blue – black/blue)

e. While slowly opening the throttle, check that
the throttle position sensor resistance is
within the specified range.
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.
Out of specification or the resistance changes
abruptly  Go to step (2).
