Hey Folks,

I have a 2017 limited, started having def issues, cheaper to delete it so away I went.

Buddy told me about bullydog setup so I purchased the unit and unlock cable.

Unplugged the 4 connections under the hood for the egr unplugged all the sensors for the exhaust and tied them out of the way, put in replacement pipes.

Ran fine all evening after we were done yesterday, got up this morning to a U02A2 code and U02A3 code.

Description: The Particulate Matter (PM) Sensor is used to determine the efficiency of the Diesel Particulate Filter (DPF) by measuring the amount of particulate matter (soot) remaining in the exhaust gas after the DPF

RAM DTC U02A2

Cause: DEF QUALITY SENSOR CONNECTOR CORROSION OR FOREIGN MATERIAL. FUSED BATTERY SUPPLY CIRCUIT OPEN/HIGH RESISTANCE. DEF QUALITY SENSOR GROUND CIRCUIT OPEN/HIGH RESISTANCE.

Shouldn't all of this be turned off with the tune?

My DEF level went zero and I am not getting any other codes or lack of power, was I suppose to leave anything connected under the truck?

I looped the pressure sensor hoses together and kept that modual plugged in but is there anything else?
