Should I be worried? DTC P0161

[kickinassrt-10]

This morning on way to work I got on it one time and when I exited the highway I saw the engine light come on. I figured it was the usual P0158 code because 2 rear cats are gone. When I pulled the code it was P0161 something with O2 sensor heat? Is this most likely just from the 2 missing cats?

I think I'm going to put in the o2 simulator bungs...

It just means there's a failure in your right rearO2 sensor. I had results for years with then zip tied to my frame
They still have to be good sensors though.

If ur running the SCT tune, you should be getting no rear O2 sensor codes.

LOL I have it the same way. I have a SCT tune but you still have to have the 02 sensor in.

Yea I have the SCT tune from Torrie. I clear the code but it still comes back. It used to be P0158.

I read you can put a bag around them and ziptie to frame. I may do this instead.

Sounds like nothing to worry about tho.

Put it in a bag and ziptie it and it will go away. Not right away it takes about 3 time of driving the truck and then it will go off.

Thanks. Thats what I'm going to do.

Besides that I got the truck back from trans shop yesterday and it drives amazing etter then ever. I just need to give it a good bath and 2 new rear tires. One rear is a spare, I tapped a edge and it put a tit on my sidewall that popped a few weeks ago. Why are the sidewalls so weak, second time it happened on same passenger rear. Truck turns like a boat.

Roger. You dont need to put them in a bag. As long as they're plugged in, you should not be getting a rear O2 sensor code. Unscrewing them and strapping them to the frame wont make a difference.

I don't understand why I am getting them then. I was always under the impression Torries tune was supposed to single that out??? Maybe I will write him an email and see if he has an update or something.
