Q: What does code P2812 mean?

Pressure Control Solenoid G Control Circuit/Open. P2812 indicates that the transmission control module (TCM) has detected an open circuit or excessive resistance in the control circuit for pressure control solenoid G, which is one of several shift solenoids inside the automatic transmission valve body. The TCM commands a specific current to the solenoid to regulate hydraulic pressure, but the circuit's electrical feedback does not match the expected value, so the TCM sets this code and may default to a limp-home mode.
