Code P3476 Description

The P3476 diagnostic trouble code (DTC) indicates an issue with the Cylinder 10 Deactivation/Intake Valve Control Circuit being high. This code typically affects vehicles equipped with Variable Valve Timing (VVT) systems, where the engine control module (ECM) can deactivate specific cylinders to improve fuel efficiency and reduce emissions. In this case, Cylinder 10 is not deactivating properly, which can lead to poor engine performance, reduced fuel economy, and increased emissions output.
