Pressure Regulating Solenoid: Testing and Inspection

Test





1. Disconnect the 2P connectors from the A/T clutch pressure control solenoid valves A and B.
2. Measure the resistance between the No. 1 and No. 2 terminals of each connector.
STANDARD: About 5.0 ohms
3. If the resistance of either solenoid is out of standard, replace the A/T clutch pressure control solenoid valves A and B.
4. Connect the No. 1 terminal of the A/T clutch pressure control solenoid valves A and B to the battery positive terminal, and connect the No. 2 terminal to the battery negative terminal. A clicking sound should be heard.
5. If not, remove the A/T clutch pressure control solenoid valves A and B.
6. Check the fluid passage of the A/T clutch pressure control solenoid valves for dust and dirt and clean the passage if necessary.





7. Connect the No. 1 terminal of the A/T clutch pressure control solenoid valves A and B to the battery positive terminal, and connect the No. 2 terminal to the battery negative terminal. Make sure the A/T clutch pressure control solenoid valves A and B move.
8. Disconnect one of the battery terminals and check valve movement.

NOTE: You can see the valve movement through the fluid passage in the mounting surface of the assembly body (C).

9. If either valve binds, or moves sluggishly, or if the solenoid does not operate, replace the A/T clutch pressure control solenoid valves A and B.
