Inspection
1.
Turn ignition switch OFF.
2.
Remove the air duct (A).

3.
Remove the air cleaner assembly.
(1)
Disconnect the breather hose (A) and brake booster intensifier hose.
(2)
Disconnect the air intake hose and then remove the air cleaner assembly (B).
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)

4.
Disconnect the solenoid valve connector (A).

5.
Measure resistance between sensor 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.
