CHECKING AND ADJUSTING THE THROTTLE
POSITION SENSOR
NOTE:
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
throttle position sensor.
Tester positive probe ! blue 1
Tester negative probe ! black/blue 2
c. Measure the throttle position sensor maxi-
mum resistance.
Out of specification ! Replace the throttle
position sensor.

d. Connect the pocket tester (Ω
throttle position sensor.
Tester positive probe ! yellow 3
Tester negative probe ! black/blue 2
e. While slowly opening the throttle, check that
the throttle position sensor resistance is
within the specified range.
NOTE:
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).
