OBD-II (EN): Cylinder 2 Deactivation / Intake Valve Control Circuit Performance
Code P3410 indicates a problem with the intake valve control circuit in cylinder No. 2 of the cylinder deactivation system (AFM/MDS). Causes may include electrical faults, a faulty valve actuator, or problems with engine oil pressure. Due to the complexity of diagnosing the cylinder deactivation system, verification by a qualified mechanic with access to a factory scanner is recommended.
Symptoms
MIL (Check Engine) light on Noticeable jerking or rough engine operation Increased fuel consumption Decreased engine performance Possible vibrations while driving Engine may run on an increased number of cylinders without deactivation capability
Possible causes
Damage to wiring or electrical connectors of the intake valve circuit for cylinder 2 Defect in the solenoid (actuator) of the intake valve Software error or failure of the engine control module (ECM/PCM) Contaminated or blocked oil passage supplying the deactivation mechanism Low or contaminated engine oil preventing correct hydraulic pressure Failure of the AFM (Active Fuel Management) or MDS (Multi-Displacement System) solenoid
