Code P3427 2015 Chevrolet Silverado Description

The P3427 diagnostic trouble code (DTC) for a 2015 Chevrolet Silverado indicates an issue with the Cylinder 4 Deactivation Solenoid Valve Control Circuit experiencing low voltage. In modern engines, cylinder deactivation technology is used to improve fuel efficiency by shutting down specific cylinders when they are not needed, such as during light load conditions. The solenoid valve controls the activation and deactivation of cylinders, and when the control circuit detects low voltage, it can lead to improper cylinder deactivation or activation, affecting the engine's performance.
