What does code P3472 mean?

Q: What does code P3472 mean?

Cylinder 9 Exhaust Valve Control Circuit High. P3472 is a generic powertrain code indicating that the powertrain control module (PCM) has detected an abnormally high voltage on the control circuit for cylinder 9's exhaust valve. This circuit typically commands a solenoid or actuator that varies exhaust valve timing or lift, and a high-voltage condition means the PCM sees voltage above the expected range, often signaling an open circuit, a short to power, or a failed actuator.
