What does code P1443 mean?

P1443 · FordEvaporative Emission Control System Vacuum System Purge Control Solenoid or Purge Control Valve Fault

P1443 on Ford vehicles means the powertrain control module (PCM) has detected a fault in the evaporative emission control (EVAP) system's vacuum purge circuit, specifically involving the purge control solenoid or purge control valve. The PCM commands the purge valve to open and allow fuel vapor to be drawn into the intake, then monitors the resulting vacuum changes; when the expected vacuum signature is not seen, it sets this code.
