Pressure Regulating Solenoid: Service and Repair
VFS (VARIABLE FORCE SOLENOID) VALVEDESCRIPTION
VFS valve controls the regulator valve and varies the line pressure from 4.5 bar to 10.5 bar according to the throttle open angle and the shift range. The holder is installed on the upper side of the case and the filter is installed to the two places on the holder outside to prevent in the strange material from flowing in the VFS.
VFS (VARIABLE FORCE SOLENOID) VALVE CONTROL FEATURE
PWM solenoid valve is controlled linearly according to the current value.
