    Could the problem be one of these two components failing?

    Anyone???

    I figured out one of the components in the photos is the Transmission Range Sensor, which i dont think that would be the issue. Perhaps the other unit that the downstream O2 sensors connect to?

    Did OP ever figure this one out? Extremely similar codes couples with a very rough idle. Briefly checked fuses and found nothing obvious.

    Was this ever solved? I literally have the same or similar codes on my 2010 mustang, the codes are:

    P0135
    P0141
    P0155
    P0161
    P0403
    P0443
    Then they repeat for some reason..
    P0135
    P0141
    P0155
    P0161
    P0403
    P0443

    For a total of 12 codes, what makes it even more difficult is this..

    The transmission on this car finally died, was sitting for months, I scored a reman transmission at a Picknpull in the central valley (Modesto CA) I removed the engine with transmission to check everything, inspected everything, and the wiring harness was taken apart and inspected as best as I could, looking for anything obvious, nothing(and yes its hard to find a break in the wire) well long story short, everything went back in and the car runs great, unfortunately the car lasted a week without the CEL(car had the SAME codes before)

    What's strange is that it all hapened after I removed the wipers and the cowl grille to replace the wiper motor, I decided to clean and remove as much junk as I could, and at the end I got the water hose and washed it wile the hood was down to avoid water from weting components in the engine bay, was being cautious since I didn't want the codes to come back, well the car got a "cold" and I'm at the same spot as before.

    It's difficult because the codes don't pop right away, its an intermittent problem that not even the 2 electrician I've seen have been able to pin point the issue..

    Most likely, one set is 'current codes' the other is 'permanent codes'.
    That's all I can do at this time till you list what each code means.
