Q27A Pressure Control Solenoid Valve 1

WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.

Pressure control solenoid valve 1 is a normally high pressure control solenoid that is used to control line pressure. The solenoid valve regulates and directs pressure to the pressure regulator valve. Increasing pressure to the regulator valve increases the line pressure.
