I have a 2016 ram 2500 I did full egr/dpf delete, went 4 inch turbo back , sinister egr delete kit, ez lynk tuning at 10,000 miles. I am now at 40,000 miles and just recently put all the stock exhaust and egr back on, and flashed the computer back to stock with the ez lynk tuner. It starts drives with no problem, no message saying it’s gonna go into limp mode or anything. But I’m running into a check engine light, when ran through ez lynk code check program, I get a U02A3 code that says lost communication with particulate matter sensor. Looked it up it’s the sensor at the back of the second dpf filter. I replaced that sensor and drove for 60 miles and shut the truck off then turned it back on and boom there it is again. Now I kept all the stock exhaust parts and sensors in storage away from any type of damage. All the plugs under the truck were taped and sealed away from the elements. Where do I go from here?
