Kia Optima Hybrid: Automatic Transaxle Control System / 35R Clutch Control Solenoid Valve (35R/C_VFS) Repair procedures

Kia Optima Hybrid (TF HEV) 2016-2020 Service Manual / Automatic Transaxle System / Automatic Transaxle Control System / 35R Clutch Control Solenoid Valve (35R/C_VFS) Repair procedures

Inspection

1.	Turn ignition switch OFF.

Remove the air duct (A).

Tightening torque:

7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)

Remove the air cleaner assembly.

(1)	Disconnect the breather hose (A).

(2)	Disconnect the air intake hose (B) and then remove the air cleaner assembly (C).

Tightening torque:

Hose clamp bolt:

2.9 ~ 4.9 N.m (0.3 ~ 0.5 kgf.m, 2.2 ~ 3.6 lb-ft)

Air cleaner assembly bolts:

7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)

•	When installing the air intake hose, the plate of the hose clamp must be in line with the stopper of the hose.

•	When installing the air intake hose, the center of the mark of hose must be in line with the throttle body rib.

4.	Remove the solenoid valve connector (A).

5.	Measure resistance between signal terminal and ground terminal.

6.	Check that the resistance is within the specification.

Removal

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.
