d. Measure the maximum throttle position sen-
sor resistance.
Out of specification ! Replace the throttle
position sensor.

e. Connect the pocket tester (Ω
throttle position sensor coupler.
Positive tester probe ! yellow terminal 3
Negative tester probe ! black terminal 2
f. While slowly opening the throttle, check that
the throttle position sensor resistance is with-
in the specified range.
The resistance does not change or it
changes abruptly ! Replace the throttle
position sensor.
The slot is worn or broken ! Replace the
throttle position sensor.
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.
