Repair procedures

Inspection

1. Turn ignition switch OFF.

2. Disconnect the oil temperature sensor connector.

3. Measure resistance between sensor signal terminal and sensor ground terminal.

4. Check that the resistance is within the specification.

Removal

NOTE

Replacing an on/off solenoid valve (SS-A, SS-B) does not require additional hydraulic pressure adjustment; however, the hydraulic pressure will need to be adjusted after replacing the VFS solenoid valve. If replacing the VFS solenoid valve; also replace the valve body assembly. (Refer to "Valve Body" in this group)
