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.

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.

a. Connect the throttle position sensor coupler

to the wire harness.

b. Connect the digital circuit tester to the throttle

position sensor.

d. Adjust the throttle position sensor angle so

the measured voltage is within the specified

range.
