2015 6.7L Cummins EGR Delete Bracket

Is the exhaust manifold pressure readable or displayable on a obd gauge like CTS, MM3 or other?

Was thinking of getting analog gauges with drive pressure, intake pressure and exhaust temp.

I just did my GDP kit- I left mine unplugged. Only driven a hundred miles or so but all is good. I loosened the fitting and laid it back toward firewall so it’s out of the way

I am unsure about PID on MM3 but I would think if it’s disabled via tuning then it wouldn’t be readable

Isn't that sensor for you exhaust brake?

Just checked my MM3 and it does display the Exhaust Pressure PID however it reads zero psi and doesn’t change.

My exhaust brake works fine so I have to assume this is normal and has been tuned out.

My guess is that I could unplug and remove the exhaust pressure sensor without any codes or exhaust brake issues?

The MM3 will not read exhaust back pressure sensor on anything newer than a 2009 model.

The 07.5-12 model trucks, the exhaust back pressure must stay plugged in.

On the 13-18 models, the exhaust back pressure sensor can be unplugged and removed.

With that unplugged on my 13’ I can still see exhaust brake parameter in EVIC when selected.
