looks like this comes up from time to time, i just had some long tube headers with "high flow" cats installed, and now i got the P0133 (02 sensor 1/1 slow response)

can i use alfaOBD to delete the "error warning ON requested" path ?

I have this come up from time to time on my 14 RT. I've replaced both O2 sensors over time with Mopar units, so I know it's not the sensors as they work fine for a while and on my scan tool you can see them active.

Now I just Clear the code and see if the sensor are adjusting properly. If so, I move on. It's only if they come back immediately that I'm concerned.

it came on about 20 miles after the headers were installed, 3rd or 4th start up

i cleared it with alfaOBD and put another 30 miles on it (and again 4 start ups)
so far it is off, but if it keeps coming back its going to annoy me
