I've been searching around the web for the past few hours. Had my y-pipe replaced a few months back with a warpspeed, and had the SES light come on. Just got around to testing it, and got what I thought 0505 code. Cleared out the light, drove around the block, and the danged light came back on! Re-tested, and got 0412 which is the same as P0134. With this, I see its a front o2 sensor. Looked on a website, and it said P0134 = Heated o2 sensor, bank 1 sensor 1. I have -no- idea where that is, any help would be appreciated. Thank you. Feel free to IM me on AIM @ aeroeck or leave feedback here.

Get underneath the car, and find your y-pipe, then look up where the pipe is going, there is an o2 sensor up there, and the other I dont know off the top of my head but the o2 sensors go into the y-pipe so just look up and down the y-pipe and you should be able to find the o2 sensors.

good luck.
