Pressure Regulating Solenoid: Description and Operation
DESCRIPTIONThe purpose of the presure regulator solenoid is to control fluid line pressure. It is controlled by the Powertrain Control Module (PCM).
OPERATION
The solenoid controls line pressure by controlling actuator feed limit fluid flow acting on internal spool valve and spring pressure. The solenoid is a normally closed solenoid valve that controls fluid pressure when operating on a duty cycle.
