Pressure Regulating Solenoid: Testing and Inspection

Test





1. Disconnect the A/T clutch pressure control solenoid valves A and B 2P connectors.
2. Measure the resistance of the A/T clutch pressure control solenoid valves A and B between the No. 1 and No. 2 terminals of each connector.
STANDARD: About 5.0 ohms
3. If the resistance of either A/T clutch pressure control 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 valve 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.





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 (A) and B (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 A/T clutch pressure control solenoid valves A and B body (C).

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