Q: What does code P3473 mean?

Cylinder 10 Deactivation/lntake Valve Control Circuit/Open. P3473 indicates that the powertrain control module (PCM) has detected an open circuit or electrical fault in the control circuit for the cylinder 10 deactivation/intake valve, which is part of a variable displacement or cylinder deactivation system. The PCM monitors the circuit for expected voltage or current and sets this code when the signal is outside the normal range, typically indicating a broken wire, poor connection, or failed solenoid.
