shown in the illustration.

2. Turn the throttle position sensor 90 degrees 

counterclockwise to set it, and tighten the screws.

3. Connect an ohmmeter between terminals 1 (ground) and 3 

(output), or between terminals 3 (output) and 4 (power).
Then, make sure that the resistance changes smoothly 
when the throttle valve is slowly moved to the fully open 
position. 

INSPECTION

DASH POT

1. Push the dash pot rod in lightly and confirm the resistance.

NOTE: Resistance increases as the rod is pushed harder.

NOTE: If the rod can be pushed in with no resistance, either 
the diaphragm or check valve is faulty.

2. Release finger and confirm that the rod returns to it's original 

position quickly.
