Code P3474 Chrysler Description

The P3474 Chrysler diagnostic trouble code (DTC) specifically relates to Cylinder 10 Deactivation/Intake Valve Control Circuit Performance. In modern vehicles equipped with cylinder deactivation technology, certain cylinders can be shut down during light-load driving conditions to improve fuel efficiency. The intake valve control circuit is responsible for managing this process in Cylinder 10. When the Engine Control Module (ECM) detects that the performance of this circuit is outside the expected parameters, it triggers the P3474 code.
