    Join the club. I get low voltage codes from my O2's. Try this, remove the O2 sensor that is bad and swap it with a good O2 sensor. See if the code follows the sensor. It may be a bad sensor. If the code does not follow the sensor you are probly running rich or maybe lean.

      what side is sensor 1 bank 2 and you are suggesting i take out the opposite side and swaping the two to find out if it is a bad sensor if it is replace that sensor and if it isnt you have any ideas.

        If I am not mistaken, bank 1 is driver's side...sensor 1 is in the manifold, sensor 2 is downstream more towards the cat.

          YEs swap bank 1 sensor with bank 2 sensor. THen see if bank 1 sensor works and bank 2 sensor is throwing the code. If so you know the code is coming from the sensor and not bank 1. Then replace the sensor. If not I dont know what to do.

          But you say its bank 1 sensor 2 throwing the code. IF thats the case I believe that is the post cat sensor. IN that case you could easily resolve it with an O2 sim.

            Read his sig, he has an O2 sim. I've been getting low voltage and high voltage since I plugged in my O2 sim, even when I still had the cat on. I've even swapped it out with Thunderracing and still the same thing. If anybody knows of a fix then please let me know.

              Did it happen soon as you put in the sim or was it a while after?

                        Yes to the question of if mine started this right when I put the O2 sim on. Here's a few posts that I've made about this. Since then, I've just gotten used to either reseting the computer once every two weeks or just staring at the SES lgiht, my ASR off light is usually off too so it's not that bad.
