Ford Tech Help Needed '07 Expedition Multiple codes
I cleared codes and it was good for about 2wks. multiple codes now
Veh cuts out, gauges go all over and read wrong, speedo quits, goes into limp mode. Shut veh off and it did not want to restart. Cleared codes and it started but went into limp mode, seems like all modules, computers and dash are losing power intermittently.
I am curious if someone has ran into this issue. Seems to me its a loose or partially broken wire or possible computer itself. In all my years of messin' with fords I have changed ZERO Computers.

I think its all pretty much related because of a power loss of sorts...
Just so it is clear I can look up codes but wondering if others have seen same issue with so many multiple codes that seem related to power failure.
So far all connectors have been taken apart and pins inspected, all grounds inspected & cleaned, inspected wiring harness but of course did not remove.
The IC
ABS
Trans
and all other modules lose power at approx the same time.
1st thing noticed is the power to test port so any diagnostic device loses power then the speedo starts bouncing the wrench light comes on, abs light, check engine, trans will no longer shift and the engine goes into limp mode, the A/C system shuts down.
It only does it when things are warm/hot never cold. Runs absolutely perfect until this happens. Even the fuel mileage is incredible... until things go south.
Yes, The PCM has been replaced. Unable to do a computer module software upgrade because with this model it cannot be done until it has completed a full drive cycle. It has never completed a full drive cycle. 6 of the 7 parameters only. Mostly because it takes that much longer here when the ambient temp into engine is over 100.4 deg f
Let me know what if anything you found out!
