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.

Can I ask what codes you are getting? It seems like the camshaft timing on bank 1 is off but I can tell if I get the codes numbers. IF you are looking for full wiring diagrams for both engines I would go to Alldata.com

It started with codes U0073-70,B1318-20,B1316-20,U1900-20,P0330-FF,P1000,P2196-FF U073-70-B1318-20,B1360-20P0175-FF,P0340-ffP0344--FF, P2195--FF. I wouldn't mind doing the AllData vehicle thing but I don't know if the PCM pinout is going to be correct because I have already looked at a couple wiring diagrams that were from 2006 that the wire color and PCM pinout didn't match what this Expedition has.

Those are a bunch of communication codes. You would be okay if the 2006 wiring and PCM was used, here are the PCM wiring for the 2006 model so you can compare to see which wiring you have. Check out the images (below). Let us know what you find.

Diagrams are incomplete. I tried testing cam sensor 1 circuit and diagram doesn't show the sensor end of the circuit. It shows it at pin 45 of the PCM and goes off the page and you can't tell where it goes from there. I ohmed out the Dkbl/O wire from the sensor to the PCM connector and have no continuity to any of the pins on the C175e connector at the PCM and found no continuity. I did continuity checks with the other 2 PCM connectors hooked into PCM. When I ohmed out the Gry/red wire from cam sensor to PCM it had continuity with many of the pins as well as the PCM grounds Blk/white wires and has continuity with the engine block/ground.Pin 45 on my wiring is tan and white and pink 44 is red which is supposed to be from cam sensor 2. Same thing goes for the upstream o2 sensors as well. Doesn't show sensor end and only shows it coming from the PCM and going off the page so no help.

Yes these are the PCM connector wiring diagrams with the camshaft sensors. Can I ask if the engine when idling has a rattling sound in the front of the engine? If so with this many miles you may have a timing chain issue which causes these kinds of camshaft sensor codes.
