Code P3435 Chevrolet Description

The P3435 code for Chevrolet vehicles indicates an issue with the Cylinder 5 Deactivation/Intake Valve Control Circuit being low. In vehicles equipped with cylinder deactivation technology, such as Chevrolet's Active Fuel Management (AFM) system, certain cylinders are deactivated under light load conditions to improve fuel efficiency. The intake valve control circuit is responsible for managing the activation and deactivation of these cylinders. When the circuit voltage falls below the specified range for an extended period, the P3435 code is triggered.
