DTC codes / P34xx · Auxiliary emission controls / P3417
P3417 indicates that the powertrain control module (PCM) has detected an open circuit or excessive resistance in the control circuit for the cylinder 3 deactivation or intake valve control solenoid. This circuit manages valves that can disable a cylinder or alter intake airflow for fuel economy or performance, and an open circuit prevents the PCM from operating that valve.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
