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.
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

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).
