Line Pressure Control Solenoid (PC-A)

WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The line pressure control (PC-A) solenoid is an inversely proportional 3-port device. The pressure output is inversely proportional to the applied DC current supplied through an electronically controlled driver, which varies the current between 0 and 1 amp from the PCM. The PC-A solenoid controls the line pressure circuits.
