Exhaust Back Pressure Gauge

[BraedenDore]

I was scrolling through the 6.7 cummins Performance page on Facebook where I saw a post about the exhaust back pressure sensor. I know my truck has one because I can see the braking power of the exhaust brake on my dash. When I select the PID on my MM3 it just shows 0 psi. I would like to monitor back pressure for peace of mind and plan on adding a 3 pillar gauge with boost and back pressure at some point but why won’t it come up on my MM3? I’ll tag @Double R Diesel as he is the MM3 master.
