Civic Sedan L4-1.5L SOHC (16 valve) (1995)
Torque Converter Clutch Solenoid: Testing and Inspection
NOTE: Lock-up control solenoid valves A and B must be removed/replaced as an assembly.
1. Disconnect the connector from the lock-up control solenoid valve A/B.
2. Measure the resistance between the No. 1 terminal (solenoid valve A) of the lock-up control solenoid valve connector and body ground, and
between the No. 2 terminal (solenoid valve B) and body ground.
Standard: 14.1 - 15.5 Ohms at 25°C (77°F)
3. Replace the lock-up control solenoid valve assembly if the resistance is out of specification.
4. Connect the No. 1 terminal of the lock-up control solenoid valve connector to the battery positive terminal and body ground. A clicking sound
should be heard. Connect the No. 2 terminal to the battery positive terminal and body ground. A clicking sound should be heard.
5. If there is no clicking, check for continuity between the engine control module (ECM) A19 or A17 harness and body ground using the Test
Harness: O7LAJ - PT3O1OA.
NOTE: Always use the Test Harness (O7LAJ PT3O1OA) for checking.
6. Replace the lock-up control solenoid valve assembly if there is continuity between the ECM A19 or A17 harness and body ground.
