Either the sensor is sending the incorrect signal (wrong sensor, or wiring to it).
Or PCM is misinterputing signal.
Was engine from same year Ford?
Is it direct replacement?
Who installed it?
Hooking up a scanner to it in live data mode will tell you what signal the PCM is receiving.
During an installation this complicated is is very possible a wire as pinched, or connector pin bent.
Is this 4.6, 5.4?
