2. Check for resistance between the terminals accord-
ing to the table.
NOTE: Resistance will vary slightly with tempera-
ture; specified resistance is at 70°F (20°C).

Actuator Test
1. Disconnect the actuator cable from the actuator rod,
and disconnect the 4P connector.
2. Connect battery power to the No. 4 terminal and
ground to the No. 1, No. 2, and No. 3 terminals.
3. Connect a vacuum pump to the check valve. Then
apply vacuum to the actuator.

4. The actuator rod should pull in completely. If the
rod pulls in only part-way or not at all, check for a
leaking vacuum line or defective solenoid.

With voltage and vacuum still applied, try to pull
the actuator rod out by hand. You should not be
able to pull it out. If you can, it is defective.
Disconnect ground from the No. 3 terminal. The
actuator rod should return. If it does not return, and
the vent hose and filter are not plugged, the
solenoid valve assembly is defective.
Repeat steps 2 through 5, and disconnect ground
from the No. 1 terminal. The actuator rod should
return. If it does not return, and the vent hose and
filter are not plugged, the solenoid valve assembly
is defective.
If you replace the solenoid valve assembly, be sure
to use new O-rings on each solenoid.
Disconnect power and ground from the 4P connec-
tor. Disconnect the vent hose from the actuator. Con-
nect a vacuum pump to the actuator vent hose port,
and apply vacuum. The actuator rod should pull in
completely. If not, the vacuum valve is stuck open.
Replace the actuator.

Actuator Cable Adjustment
1. Check that the actuator cable moves smoothly with
no binding or sticking.
2. Measure the amount of movement of the output
linkage until the engine speed starts to increase. At
first, the output linkage should be located at the
fully closed position. Free play should be 5 ± 0.5 mm
(0.20
±
0.02 in).
