What does code P1407 mean?

Q: What does code P1407 mean?

EGR No Flow Detected. P1407 on Ford vehicles means the powertrain control module commanded the exhaust gas recirculation (EGR) valve to open but saw no corresponding change in the manifold absolute pressure (MAP) sensor or differential pressure feedback EGR (DPFE) sensor signal, indicating no exhaust flow through the EGR system. The computer monitors the pressure change across the EGR orifice and flags the code when the expected drop or rise does not occur within a calibrated time window.
