What does code P2D15 mean?

Q: What does code P2D15 mean?

Exhaust Flow Control Valve C Control Circuit High. P2D15 indicates that the powertrain control module has detected a high-voltage condition on the control circuit for the exhaust flow control valve, which is used to manage exhaust gas flow and backpressure. The computer commands the valve to a specific position but sees the control circuit voltage stay above the expected threshold, suggesting an open circuit, short to power, or a faulty valve actuator.
