ACTUATOR TESTS
Resistance Test (1991)
Disconnect actuator connector. Resistance between terminals
No. 1 and 2 should be 20 ohms. See Figs. 17-21. If resistance is not
correct, replace actuator assembly.
Operational Test (1991)
1) With connector disconnected, connect battery voltage to
terminal No. 1. See Figs. 17-21. Ground terminal No. 2. Connect
ammeter between positive side of battery and terminal No. 1 of
actuator connector.
2) Solenoid should make a click sound. Ammeter should read .
5-.7 amps. Connect positive side of battery to terminal No. 4 and
ground terminal No. 3. Actuator should pull in and stop.
3) While actuator is moving in, ammeter should read less than
.5 amps. When actuator travel reaches midpoint, disconnect terminal
No. 1 from positive side of battery. Actuator should return to
original position. If actuator does not test correctly, replace
actuator.
4) Reverse connections of terminals No. 4 and 3 in step 2).
Connect battery voltage to terminal No. 3 and ground terminal No. 4.
Actuator should move out then stop. While actuator is moving, ammeter
should read less than .5 amps.
1992
Remove actuator. Apply vacuum to actuator. Actuator linkage
holder should move more than 1.38" (35 mm). Actuator diaphragm should
hold vacuum. Replace actuator if actuator does not test correctly.
VEHICLE SPEED SENSOR TEST
1) Remove instrument cluster. See INSTRUMENT CLUSTER under
REMOVAL & INSTALLATION. Check continuity between vehicle speed sensor
terminals at instrument cluster. See Fig. 30 or 31.
2) Ensure continuity pulses on and off 4 times per revolution
of speedometer shaft connection. If continuity is not as specified,
replace vehicle speed sensor.
