Lockup Solenoid Valve

Output Duty Inspection






1. Connect the (+) terminal of a dwell meter to terminal 2C of the powertrain control module (Transaxle) and the (-) terminal to a ground.
2. Drive the vehicle.

Note: The dwell meter indicates the OFF duty ratio.

3. Verify the duty ratio in the lockup condition.

Dwell Angle/Duty Ratio Relationship:

4. If not as specified, check the powertrain control module (Transaxle) and lockup solenoid valve.

Manual Operation Test






1. Disconnect the solenoid connector.
2. Accelerate the vehicle from 0 mph, and determine the gear position by observing the engine speed (drum speed). 1st gear is approximately 4,250 rpms. Third gear is approximately 1,500 rpms. Verify the gear position of each range.






4. If not within the specification, check the oil pressure or transaxle.
