So I have a 2013 Focus in the shop and has had a slight accident on the front but nothing to major but have this code P06A7 and it does not like to run! Does anyone know what the cryptic message of
"Sensor Reference Voltage "B" Circuit Range/Performance" really means?
Well the code is gone but now has a no crank when the start button is pushed. All modules check fine, (pass self test) no codes on scan, all fuses and relays good, just no crank! engine cranks if jumped at starter, Keys are ok and working
Ideas of where to go with this?
Well no physical contact that I can see but have taken a lot of time to go through all wires in the under hood area with hopes of finding a damaged harness. There was one harness that was damaged on the engine and has been replaced but I am wondering if it caused some ECU damage. All modules self test good but I suppose one could be corrupt, perhaps a ford re flash is the needed repair in this case, I just cant seem to find a real physical issue.
Well it's basically just saying you are losing vref to some of the sensors. Didn't look into exactly what ones at the moment. Are you sure no other codes present? With loss of 5 volt reference should have other codes. Try checking for 5 volts at various sensors to see if it's there
Well no warranty, part of the collision repair but has turned into a bit more than expected.
I did get the diagnostic break down from ford and have gone through all tests and related PIDS with my VCM2 but have made it as far as the no signal from ECU. It is asking me to check wiring and connectors from the starter relay to ECU but I have no diagrams electrically speaking to complete the trouble shooting so looks like a trip to the dealer unless I can get diagrams. I have a feeling there is an internal problem in the ECU.
I could ask at ford again but they were less than happy to assist with the first request, not sure how the wiring diagram request would go!
