d. Connect the pocket tester (Ω
throttle position sensor.

the throttle position sensor resistance is with-
in 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.
