A/T Clutch Pressure Control Solenoid Valve A and B Test

WARNING: This page is about a different car, the 2004 Honda Odyssey, 2003 Honda Odyssey, and 2002 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect the 2P connectors from the A/T clutch pressure control solenoid valves A (A) and B (B).

Measure the A/T clutch pressure control solenoid valves A and B resistances at each solenoid valve connector.
Standard: 3-10 Ω.
If the resistance of either solenoid is out of standard, replace A/T clutch pressure control solenoid valves A and B.
Connect the No. 1 terminal of 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. Remove A/T clutch pressure control solenoid valves A and B, if no sound is heard.
Check the fluid passage of the A/T clutch pressure control solenoid valves for dust and dirt, and clean the passage if necessary.
Connect the No. 1 terminal of 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.

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 solenoid valve body (C).
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.
