Q: What does code P2DD9 mean?

EVAP System Leak Detection Pump Control Circuit Performance. P2DD9 means the engine computer has detected that the EVAP system leak detection pump control circuit is not performing as expected, typically because the pump motor's electrical current or response does not match the commanded state. The computer monitors the control circuit for opens, shorts, or abnormal current draw and sets this code when the circuit's behavior falls outside the calibrated range.
