XFI UEGOS V dropping, code 16 problems

    Been trying the new 2.0 software, and noticed I kept loosing Learning. Checked into why and found that I kept getting code 16. Logged a trip to walmart and found my UEGOS dropping WAY down into RED .10

    Cant say how long this has been a problem, never noticed cause I never checked for codes. O2 correction stayed OK. I recently moved the O2 sensor after the turbo into a short 24" down pipe (this is a REAR mount turbo truck). But I cant see how that would be a problem. It seems to occur after making a pull in boost as the graph below shows.

    Any ideas?

    looks like you found your problem. Wonder if the sensor went bad from being pre-turbo sooner.

    Yup, drove the truck with the spare sensor. All looked and ran well. Thanks Brian.
