Normal Operation and Fault Conditions
WARNING: This page is about a different car, the 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The TCM controls the hydraulic line pressure by varying the amount of current applied to the LPC solenoid. When no current is applied to the LPC solenoid, the LPC solenoid is fully opened, resulting in the maximum amount of hydraulic pressure to the main pressure regulator valve. When maximum current is applied, the LPC solenoid is fully closed, resulting in minimum pressure to the main pressure regulator valve.
