CODE P0194 HELP.

recently took my truck to the dealer to get some things done, and this code popped back up a day after i got it back. so i took it back in to talk to em, and they said they could only reset my pcm but if they did that the truck might run like sh*t and or not run at all since my dpf is deleted and is clearly in OFF mode. they said since my dpf delete is just a piece of pipe welded in and my sensor just hangs there, their test read "no back pressure" since the sensors isnt hooked in, i was told thats why im getting this CEL, and that i needed to put in a resistor to connect to the sensor to tell the computer to read normal.
who else has had this prob?? i need some feedback and info PLEASEEEEEE...

What tuner are you using? Or did you have the PCM programmed to turn off the DPF instead of using a tuner?

i'm going to probably use the SCT livewire ts #5015
and hopefully it'll work good with the dfp delete.

Just make sure you get one that's capable of deleting the DPF, I think that's 5015R (Race version). I don't think the normal 5015 will work for you. I know SCT had some issues with the EPA a while back and paid a huge fine and had to quit making race tuners. I think you can still load third party tunes on an SCT to do the deletes, but that'll cost you a little more.

Be sure you know what you're buying.
