It isn't - I checked my sensor after 2 years and still clean as a whistle - It is almost 24"inches downstream connected to a T- fitting and a 1/4" brake line .I wonder how the particulate is effecting ya'lls sensors...
Why not post some examples of them complaining - are they deleted trucks - mine has worked flawlesly for two years now . The factory sensor is just down stream less than a foot and they also work for years so whats the problemWow, that's interesting... cause on everyone else's it seems to be clogging up gauges. I'm suprised it dosn't clog sensors too.
