Shift Solenoid: Testing and Inspection

SOLENOID VALVES INSPECTION [GF4A-EL]
Inspection Of Resistance
1. Disconnect the negative battery cable.
2. Remove the resonance chamber, fresh-air duct and air cleaner component.
3. Disconnect the solenoid valve connector.
4. Measure the resistance between terminals A through G and a ground.





5. If not correct, check the wiring harness or replace the solenoid valve(s), if necessary.
6. Connect the solenoid valve connector.
7. Install the air cleaner component, fresh-air duct and resonance chamber.
8. Connect the negative battery cable.

Inspection Of Operation
1. Disconnect the negative battery cable.
2. Disconnect the solenoid valve connector.





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

Inspection Of Output Duty
Pressure Control Solenoid
1. Connect the (+) terminal of a dwell meter to terminal 81 at the powertrain control module and the (-) terminal to a ground. Set the dwell meter selector to the 4 cylinder position.
2. Engage the parking brake and use wheel chocks at the front and rear of the wheels.
3. Start the engine.
4. Depress the brake pedal firmly.
5. Shift the selector lever to D range.

CAUTION: It the accelerator pedal is pressed for longer then 5 seconds while the brake pedal is pressed, the transaxle could be damaged. Therefore, do step 6 within 5 second of each other.

NOTE: The dwell meter indicates the OFF duty ratio.





6. Depress the accelerator pedal slowly and verify that the duty ratio charges as shown in the graph.
7. If not as specified, check the powertrain control module and pressure control solenoid, (Refer to Inspection of resistance.)
