P0748 Pressure Control Solenoid Valve -Hyundai ACCENT(RB) 2012

General Description Pressure Control Solenoid (Linear Solenoid) : With the duty control which uses higher frequency(600Hz), instead of the existing PWM type which adapts low frequency(60Hz) to control,spool valve can be conrolled precisely. In PWM control,the amount of oil flow is determined by the duration of "ON"signal among continuously repeated ON/OFF signals. In Pressure Control, the amount is decided by how widely spool valve open the passage of going through.
