Code P0967 2017 GMC Sierra Description

The P0967 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates an issue with the Pressure Control Solenoid Valve 2 Control Circuit registering high voltage. This solenoid valve is a crucial component of the transmission system, responsible for regulating hydraulic pressure within the transmission. When the control circuit detects high voltage, it means that the solenoid is receiving more electrical current than expected, which can lead to improper operation and potential damage to the transmission.
