Torque Converter Clutch Solenoid: Testing and Inspection

1. Disconnect the 3P 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 3P connector and body ground.




3. Measure the resistance of the shift control solenoid valve A between the No. 3 terminal of the 3P 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 standard.
5. If the resistance is within the standard, connect the No. 1 terminal of the 3P connector to the battery positive terminal. A clicking sound should be heard.
- Connect the No. 3 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 either terminal is connected to the battery positive terminal.
