Torque Converter Clutch Solenoid: Testing and Inspection

1. Disconnect the 2P connector from the lock-up control solenoid valve/shift control solenoid valve A assembly.
2. Measure the resistance of the lock-up control solenoid valve between the No. 1 terminal of the 2P connector and body ground.




3. Measure the resistance of the shift control solenoid valve A between the No. 2 terminal of the 2P connector and body ground.

STANDARD: 12 - 25 ohms

4. Replace the lock-up control solenoid valve/shift control solenoid valve A assembly if either resistance is out of specification.
5. If the resistance is within the standard, connect the No. 1 terminal of the 2P connector to the battery positive terminal. A clicking sound should be heard. Connect the No. 2 terminal to the battery positive terminal. A clicking sound should be heard. Replace the lock-up control solenoid valve/shift control solenoid valve A assembly if no clicking sound is heard when connecting either terminal to the battery positive terminal.
