2024年4月17日 · I replaced both upstream and downstream NOX sensors but I still have one remaining code (U029E - Network Communication) and the DEF countdown continues. I tried clearing the code with a scan tool, disconnecting both batteries for an hour and even had the truck idle through REGEN all as an attempt to restore communication with the NOX sensors.

2019年2月20日 · Thank you for reading my post. I have a 2014 Ram 2500 CCLB that threw this code and gave me the 150 mile countdown until 5MPH.

2018年9月27日 · U029E: This one seems to be emissions related, but I can't find anything on U029E specifically. And then after about 3 minutes of driving the service Electronic Throttle Control message comes up. From what I have read, this could be …

I may try the re-gen method or just shrug and move to next steps, I believe I am running out of test KM now lol...

2014年9月7日 · I just bought a used 2012 with 92k miles, the dealer did a bunch of work on it, including changing some o2 sensors, before I picked it up. Just after driving it off the lot the engine light came on. I hooked up my code reader a erased 4 codes all having to do with o2 sensors, then the U011A code...
