Good day everyone.

We bought a 2017 Ford Expedition EL 3500 a year ago second hand. It has been spitting out the code P06A7. We have changed - spark plugs, coils, airflow meter, 2x map sensors and TPS (throttle position sensor). No change.

We are currently looking for the wiring diagrams and colour diagrams for the ECU and the 5V Sensor Circuit.

Is there anyone that can assist us with this?

Looking forward to hearing from you.

Hello there,

I don't have any wiring diagrams or anything. I would check all of your grounds, with this being a 5v issue I would check the connections at the PCM. I would pull the connections and clean gently with electrical cleaner and dry compressed air (or canned air) if you dont want to clean them I would at least unplug and replug them, a little corrosion on a pin can cause all sorts of fun issues and be hard to find, and working the connection can sometimes clean it up.

Another option is to get a bluetooth OBD scanner and use forscan to read all of the sensor voltages and maybe that can help pinpoint a sensor.
