Default 6.7 with DPF removed and a smarty - setting invisible code

I have a 6.7 and pulled the DPF as well as egr and cooler. i have the egr motor still plugged in and ziptied to the side .... everything done correctly as i understood it. About every 500 miles i get the overhead ding ding see dealer now .... after another couple hundred miles it feels like it derates itself .... when i plug in the smart it shows no codes, i clear the no codes and poof back to good to go.

Anyone else have this?

I would re-check the plugs and connectors you pulled and make sure you got them all, and not pull one you need like the EGR motor.

rechecked, found no issues.

I will just continue clearing the code. i have seen a few other complaints about this.

Default I get the same thing

I get the phantom as well. I just reset the invisible code using the smarty and it is ok for another several hundred miles.

I wish I would not have to though.

I've had the "See Dealer" message come up one time in the 20Kmiles I've racked up since my deletes. I cleared it and it hasn't come back. For what it's worth, I'm running 14ME. I never noticed a loss of power at all when it did come up though.

mine will start to lose power after about 2 weeks of not clearing it. The wife drives it everyday .... i know because she tells me the dodge is getting slower and slower ... i will clear it and she notices right away.

we had similar power issues when running the H&S sims, before the smarty ...

I got a pm from diesel pap, basicly asking me to go over what i have done ... as i was doing my run down of explaining i came to the pressure sensor. Now, i have the plumbing removed BUT had the sensor still plugged in. I just now unplugged it. Perhaps this is where i went wrong ?

The one with the 2 hoses coming off it. Up against the floorboard.

Light came on immediatly with it unplugged ... plugged back in, cleared the code ... gonna leave it alone.


I am thinking of going with a bullydog watchdog, that should clear the code whenever i want it to and get a nice display as well.
