Q: What does code P2DFD mean?

EVAP System Purge Pump Performance. P2DFD indicates that the powertrain control module has detected a performance fault in the electric purge pump that is used on some evaporative emission (EVAP) systems to pressurize the fuel tank for leak testing. The computer monitors the pump's ability to build and hold pressure during a self-test, and it sets this code when the pump's electrical current or pressure output does not match the expected profile.
