PWM Solenoid Secondary Valve

The PWM solenoid secondary valve influences secondary valve movement, hence belt tension via secondary pulley chamber pressure. The secondary pressure solenoid further modulates the pressure acting on the secondary pressure valve. This optimizes the secondary pressure and hence minimizes losses and improves fuel consumption.
