THROTTLE BODIES
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.

c. Measure the throttle position sensor voltage.
d. Adjust the throttle position sensor angle so
the measured voltage is within the specified
range.
