The real deal: The 08+ focus uses a mechanical returnless fuel system. This is different from other years. There is no PID for monitoring fuel pressure because of this.
The returnless system of the o8 and up has the same type cannister and a fuel rail psi sensor just like the early years , The ECU is getting a reading of fuel psi from somewhere because I saw this on a Ford scan tool , whats changes that makes the o8 Diff from the o9 or o7 ? If Ford can read and the ECU read this signal why cant SCT read it ?
