P2815Pressure Control Solenoid G Control Circuit High

P2815 indicates that the transmission control module (TCM) has detected an abnormally high voltage on the control circuit for pressure control solenoid G, which is one of the hydraulic pressure regulators inside the transmission valve body. The TCM commands a specific current to the solenoid to regulate clutch pressure, and when the feedback voltage on the control wire exceeds the expected range, the circuit is flagged as high.
