P2814 on Cadillac

Pressure Control Solenoid "G" Control Circuit Low

Critical1 Cadillac model affectedSystem: Powertrain

P2814 on Cadillac vehicles indicates pressure control solenoid "g" control circuit low. Au7o has documented this code across 1 Cadillac model — most commonly on CT5. 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.

Common Causes of P2814

  • •Faulty pressure control solenoid "G" (internal short)
  • •Wiring shorted to ground in the solenoid circuit
  • •Chafed or pinched internal harness wiring
  • •Corroded or damaged connector
  • •Low or contaminated transmission fluid
  • •Faulty transmission control module
