I believe this is a pressure sensor that works off the EGR.

It’s mounted on the passenger side and taps into the middle of the exhaust manifold.

If this is what it is, was it shut off with the MM3 Tuner Lite?

Was thinking of mounting my egt sensor in that port!

It’s on my 2016 Ram!

Thanks you all!
