Hey all,

I am trying to figure out what the best fix would be for the O2 sensor issue on my truck. 2015 RRS HSE V6 48k miles.

I see the technical bulletin LTB00671NAS6, so it looks like water is hitting the sensors and throwing a bunch of codes. I have seen someone say to just tape them up, but was wondering if that's the fix, or if getting new sensors will fix it? Its getting a little old having to clear the codes every week or so. I have been trying to search different forums as i would imagine people have been over this, but I haven't found much at all.

These are throwing even when its completely dry outside, so I don't know if its condensation or something that is hitting the sensors? Any help would be appreciated for what you guys feel is the best fix.

 

The fix is to replace the effected sensor, then update the Engine Control Module.
Water is a byproduct of combustion, so there will always be moisture/condensation in the exhaust. I think the software update changes how the ECM controls the internal heaters to prevent future failures. however current failures require sensor replacement.
