P3413 Cylinder 2 Exhaust Valve Control Circuit/Open

P3413 belongs to the exhaust half of the cylinder 2 block and reports an open control circuit for a separately driven exhaust valve actuator. No manufacturer documents this code publicly. The engines known to deactivate cylinder 2, GM's L84 V8 and the 3.6 L V6, switch intake and exhaust valves through one control valve per cylinder and therefore report circuit faults as P3409. The code would only apply to designs with their own control valve for the exhaust side; a GM patent application instead switches both sides with one shared valve and merely staggers them, exhaust first. CARB requires a continuity check for such output components. P3414 to P3416 complete the exhaust group. The driver would see a lamp and lose deactivation.

Likely causes

Open wire or connector to the cylinder 2 exhaust actuator
Actuator coil open
Engine control module driver fault

Symptoms

  • Check engine lamp on
