a. Disconnect the throttle position sensor cou-
pler from the throttle position sensor.
b. Remove the throttle position sensor from
the throttle body.
c. Connect the pocket tester (Ω × 1k) to the
throttle position sensor.
d. Measure the maximum throttle position sen-
sor resistance.
Out of specification → Replace the throttle
position sensor.
e. Connect the pocket tester (Ω × 1k) to the
throttle position sensor.
f. While slowly opening the throttle, check that
the throttle position sensor resistance is
within 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
gradually when turning the throttle, since the
readings (from closed to wide-open throttle)
may differ slightly from those specified.
