Code P0159 before update

[wesalbert]

First I would like to say that I have NOT flashed the PCM yet. This is STOCK.
This weekend is the first time that I have really driven the truck some miles since I got it. I made a 40-50 mile trip and my check engine light came on. I pulled out P0159-O2 SENSOR 2/2 SLOW RESPONSE.
I reset the codes, then about 60 miles again, same code.
Will your program solve my issue, or is there something else I should be looking for?

your passenger side after cat sensor may be bad.....warranty issue if so...

got catless mids. I wouldnt think they would cover that anymore.
Good to know what one it is.....

I thought you said you were stock...catless mids will cause 139 & 159 codes..........you need electric O2 sensors or some say you can hang your after cat O2 sensor under the truck...didnt work for me though..others will chime in with other alternatives..

sorry, meant the programming was stock since my tuner is on the way. Do you have a link, part #,or where to get the electric O2 sensors.
I saw the post about the parts to move it out of the airflow buy getting some part and drilling it out. But I also saw someones post of how it hit the tranny on the right side I believe.
What was your solution?

I put electric sims on my truck from Roe (click link below)....Try hanging the rear sensors under the truck first..this works for some...make sure to plug the holes in the mids..

Just crawled under the truck.
O2 sensors are installed with the "spacers". I dont remember where that link is, but I know I saw it on the forum somewhere.
Another thing I noticed when I was under there was that there is a hole in the side of the magnaflow where the support broke off and the muffler is just hanging there.
Guess it is also time for a new cat back. :argh:

I can turn off the rear 02 in the tuner and send you an update also. Repair what you have first and we'll do that next.
