P3415
ŚredniLow Voltage in the Exhaust Valve Control Circuit of Cylinder 2. The code indicates an electrical problem in the cylinder deactivation system.
OBD-II (EN): Cylinder 2 Exhaust Valve Control Circuit Low Voltage
Code P3415 means too low voltage in the control circuit of the second cylinder's exhaust valve – this is a component of the cylinder deactivation system used in GM (AFM) and Dodge/Chrysler (MDS) engines. The cause may be a damaged solenoid, wiring problem, or too low engine oil pressure. Diagnosis by a mechanic with an appropriate scanner capable of testing the cylinder deactivation system is recommended.
Symptoms
Increased fuel consumption Rough engine operation or vibrations Check Engine light (MIL) on Possible engine entry into limp mode Noticeable jerking or lack of smoothness while driving Possible disabling of the cylinder deactivation system (AFM/MDS)
Possible causes
Damaged or shorted solenoid for the exhaust valve of cylinder 2 Open or short circuit in the wiring harness supplying the solenoid Corrosion or damage to the solenoid electrical connector Low engine oil pressure (the deactivation system is hydraulic) Damaged engine control module (ECM/PCM) – rarely Contaminated or degraded engine oil blocking hydraulic passages Mechanical damage to the cylinder deactivation valve
