P2814: Pressure Control Solenoid "G" Control Circuit Low
2 vehicles · 1 makes · $450-$6,500 repair
Most Reported On
P2814 is an OBD-II diagnostic trouble code meaning “Pressure Control Solenoid "G" Control Circuit Low.” This code means the transmission control module detected a low-voltage (often a short to ground) condition in the control circuit for pressure control solenoid "G". This solenoid regulates hydraulic pressure that applies the transmission clutches and bands. A low/shorted circuit prevents proper control of that solenoid, which can cause harsh or erratic shifting, slipping, or limp mode. It is generally an electrical wiring or solenoid fault. This code is most commonly reported on 2021-2025 Cadillac Escalade ESV, and 2020-2021 Cadillac CT5, with repair costs ranging from $450 to $6,500.
