Code P0777 2020 Honda CR-V Description

The P0777 diagnostic trouble code (DTC) specifically relates to the CVT Driven Pulley Pressure Control Solenoid Valve being stuck ON in a 2020 Honda CR-V equipped with a Continuously Variable Transmission (CVT). The CVT Driven Pulley Pressure Control Solenoid Valve is responsible for regulating the hydraulic pressure within the transmission system, which in turn controls the operation of the driven pulley. When this solenoid valve gets stuck in the ON position, it can lead to an abnormal increase in hydraulic pressure, causing issues with the transmission's shifting behavior and overall performance.
