Valve Body: Testing and Inspection

INSPECTION OF RESISTANCE
Solenoid Valves
1. Disconnect the negative battery cable.
2. Remove the battery.
3. Disconnect the solenoid valve connector.
4. Measure the resistance between terminals A-H and a ground.







5. If not correct, replace the solenoid valves.
6. Connect the solenoid valve connector.
7. Install the battery.
8. Connect the negative battery cable.

INSPECTION OF OPERATION
Solenoid Valves
1. Disconnect the negative battery cable.
2. Disconnect the solenoid valve connector.




3. Apply battery voltage to each solenoid terminal A through H.
4. Verify that each solenoid control valve operates with a "click".
5. If the "click" is not heard, replace the solenoid valve.

OUTPUT DUTY INSPECTION
Pressure Control Solenoid




1. Connect the (+) terminal of a dwell meter to terminal 1F of the transaxle control module and the (-) terminal to a ground. Set the dwell meter selector to the 4 cylinder position.
2. Turn the ignition switch to ON.

NOTE: The dwell meter indicates the OFF duty ratio.





3. Verify the duty ratio by depressing and releasing the accelerator pedal.


NOTE: The relationship between the dwell angle (°) and duty ratio (%) is as follows:







4. Depress the accelerator pedal slowly and verify that the duty ratio charges as shown in the graph.
5. If not as specified, check the transaxle control module, dropping resistor, and pressure control solenoid.


Torque Converter Clutch Solenoid Valve




1. Connect the (+) terminal of a dwell meter to terminal 1 M of the transaxle control module 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 TCC condition.
4. If not as specified, check the transaxle control module and TCC solenoid valve.
