SOLENOID VALVE INSPECTION

BHE051321101W01

  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.)
