Ok this is a new thread because the last one was LONG .
To update if anyone forgot the last work done on the car was at ford service when they overfilled the oil then lied and said they didn’t see the U0401:81. So I got the oil fixed and the car is driving ok it also doesn’t have any check engine or warning lights .
But At this point I’m still getting the U401:81 code with the think car and forscan . Also the car has a backfire at start up sometimes too . Ok so I have been reading and trying to get ideas about what the issue could be . I found a post here from 2012 maybe talking about the same issue I’m having ? I will post a screen shot to show what I’m talking about . It is also still getting the weird erratic yaw readings and wheel speed when car parked with key on engine off . Besides just the crazy yaw the think car is showing me it is also showing weird numbers for the power steering . Ok that said does that sound like a steering rack issue ? Or something else I’m looking for ideas before I start taking it apart again lol
This is what forscan is telling me
