Actuator Test
Special Tools Required
Vacuum Pump/Gauge, 0 - 30 in.Hg
A973X-041-XXXXX
1. Disconnect the actuator cable from the actuator rod and disconnect the 4P connector (A).
2. Connect battery power to the No.4 terminal and ground the No.1, No.2 and No.3 terminals.
3. Connect a vacuum pump to the vacuum hose, then apply vacuum to the actuator.
4. The actuator rod (A) 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.
5. 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.
6. Disconnect ground from the No.3 terminal. The actuator rod should return. If it does not return, but the vent hose and filter are not plugged, the solenoid valve assembly is defective.
7. Repeat steps 2 through 5, and disconnect ground from the No.1 terminal. The actuator rod should return. If it does not return, but the vent hose and filter are not plugged, the solenoid valve assembly is defective.
8. If you replace the solenoid valve assembly, be sure to use new O-rings on each solenoid.
9. Disconnect power and ground from the 4P connector. Disconnect the vent hose from the actuator. Connect 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.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
