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
M1131009800053
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.
NOTE: If the rod returns slowly, the check valve is faulty.
