Hey, I'm looking for a wiring diagram, engine harness, Sensors, 2001 Expedition Eddie Bauer , 5.4l

Throwing out different trouble codes after 5 - 10 miles or even at startup. Runs great, but I think high consumption.

First , O2 Sensor bank 1 Sensor 2 heat circuit,
Replaced all O2 Sensors, but comes back.

P1401 Egr Pressure
Hoses good, just 5.0v I think faulty, ordered new one. Waiting for it.

Only sometimes,

P0100 Mass Air Flow Sensor

P0014 camshaft to early., Sensor new. But back. Sometimes

Can someone send me a wiring diagram?

The engine starts and runs great, on LPG and Gasoline, sometimes I thinks he's running less of power, in the hills.

286000miles, DR vehicle, so the electric can be tricky, but he's in a good state ...

Thanks ,

Already searched a lot in your threads, didn't find anything.

Is the heater integrated into the O2 Sensor assembly? That is, they're not individually changeable?

Just curious because I recently scanned a friend's 2003 Toyota Avalon with the same problem but on a different circuit. He took it to his shop but I haven't heard the results yet.
