Code P0777 2017 Honda CR-V Description

The P0777 code on a 2017 Honda CR-V indicates a problem with the CVT Driven Pulley Pressure Control Solenoid Valve being stuck ON. This solenoid valve is responsible for controlling the pressure in the CVT (Continuously Variable Transmission) driven pulley, which is crucial for the proper operation of the transmission system. When this solenoid valve gets stuck in the ON position, it can lead to issues with the transmission's performance, potentially causing erratic shifting, loss of power, decreased fuel efficiency, and even transmission failure in severe cases.
