Vehicle is a 2006, have since learned that it is a 2010 engine. Have no cam sensor signal bank 1 and appears bank 1 sensor 1 is stuck lean. Have swapped 02 sensors with no change in performance or voltage on bank1. Supposedly cam chains and factory phasers done not long ago. Power balance test on scan tool shows all cylinders on bank 1 have low readings. Wire colors/PCM pinouts for cam sensor and 02 sensors don't seem to match vehicle schematics. Questioning if 2010 wiring harness was used with with 2006 PCM. Looking for wiring schematics for 2006 and 2010 Expeditions/ F150. Also 2010 F150 was supposed donor vehicle for engine swap. Wiring schematics for cam sensors and 02 sensors and testing procedures for sensors. Questions of where wires terminate at pcm and what other sensors they may tie into.
