O2 Sensor

If it does come on, the askatech web page does work, just search the reference number.

You can thank Snap On for the info, straight off the scanner.

Keep in mind all of those codes are for the bank 1 sensor 1 O2, you still have 3 more sensors which none of those codes relate to.
Other then it would say the same thing just a different code and sensor.

Hi Guys,

I'm new to the forum but not to building, repairing, or tuning cars. I think the O2 code might be P0134 that trevcda got. I just got my wife a 00 Yukon XL and after a few days it threw the same code. I am replacing it today and that should clear it out. I know from experience that you NEVER clear a code until you get the info for the code and know what you need to do to fix it. I learned that when I cleared the knock sensor code on a turbo car I had and destroyed the engine within 72 hours.

That was all great info kcb37. It is appreciated. Here is a pic of my wife's Yukon so you can see what I am working with.

Easy fix. Replace all 4 O2 sensors and be done with it... Eventually that code will keep coming back.
