SOLENOID VALVE INSPECTION

Caution

• Water or foreign material entering the connector can cause poor connections or corrosion. Be sure that water or foreign material do not enter the connector when disconnecting it.

Resistance Inspection (On-Vehicle)

1. Remove the engine cover.

2. Remove the battery cover.

3. Disconnect the negative battery cable.

4. Remove the catalytic converter. (See EXHAUST SYSTEM REMOVAL/INSTALLATION.)

5. Remove the insulator.

6. Disconnect the solenoid valve connector.

7. Measure the resistance between the following terminals.

• If not within the specification, perform the operating inspection. (See Operating Inspection.)

ATF temperature: 20-80 °C {68-176 °F}

Terminals	Solenoid valve	Resistance (ohm) (Reference value)
E-J	Shift solenoid A	2.7-4.4
F-J	Shift solenoid B	2.7-4.4
G-J	TCC solenoid	12.1-16.0
H-J	Shift solenoid C	2.7-4.4
I-J	Shift solenoid F	2.7-4.4
K-J	Pressure control solenoid	12.3-16.3

8. Connect the solenoid valve connector.

9. Install the insulator.

Tightening torque

8-11 N·m {82-112 kgf·cm, 72-97 in·lbf}

10. Install the catalytic converter. (See EXHAUST SYSTEM REMOVAL/INSTALLATION.)

11. Connect the negative battery cable.

12. Install the battery cover.

13. Install the engine cover.

Operating Inspection

1. Remove the engine cover.

2. Remove the battery cover.

3. Disconnect the negative battery cable.

4. Remove the catalytic converter. (See EXHAUST SYSTEM REMOVAL/INSTALLATION.)

5. Remove the insulator.

6. Disconnect the solenoid valve connector.

Caution

• Do not apply the battery positive voltage to terminals E, F, G, H, I and K for more than 3 s.

Note

• Because the operation sound of the valves is not strong, inspect in a quiet place.

7. Apply battery positive voltage to terminals E, F, G, H, I or K and battery negative voltage to GND, and verify that operation sound is heard from solenoid.

• If the "click" is not heard, inspect the transmission wiring harness.

– If the transmission wiring harness is normal, perform the resistance inspection

(off-vehicle inspection).

– If there is a problem, repair or replace the transmission wiring harness.

8. Connect the solenoid valve connector.

9. Install the insulator.

Tightening torque

8-11 N·m {82-112 kgf·cm, 72-97 in·lbf}

10. Install the catalytic converter. (See EXHAUST SYSTEM REMOVAL/INSTALLATION.)

11. Connect the negative battery cable.

12. Install the battery cover.

13. Install the engine cover.

Resistance Inspection (Off-Vehicle)

1. Remove each solenoid valve. (See SOLENOID VALVE REMOVAL/INSTALLATION.)

2. Measure the resistance of each solenoid valve individually.

• If not within the specification, replace the solenoid valve. (See SOLENOID VALVE REMOVAL/INSTALLATION.)

Pressure control solenoid

Resistance (reference value)

12.3-16.3 ohms

Shift solenoid A, B, C and F

Resistance (reference value)

2.7-4.4 ohms

TCC solenoid

Resistance (reference value)

12.1-16.0 ohms

3. Install each solenoid valve. (See SOLENOID VALVE REMOVAL/INSTALLATION.)
