Thread: O2 sensor

I had my car scaned for codes at a local garage. No codes were found and it never had any in the memory. The Mech took it out for a drive with the scanner hooked up and he said that #1 O2 was reading between 0 - 850 and that #2 was stuck @ 652. I than took to the dealer where i bought it from and they told me, after they check for codes only that everything is ok. They did not take it out on the road to get a reading of the O2's. and everything is ok.

So my question is do i have a O2 sensor that is screwed up?
Under driving conditions it seems i have a problem. but as for codes its ok.

The car is under warrenty and the sensors are covered IF they are no good



Can some shed some light on this for me

Thanks in advance

dont go to that shop anymore.

the front (bank 1) is for o2 readings, fuel mapping, etc. bank 2 doesnt exist.

the rear one is just used for emissions, thats it.

ohhhh so that means that my sensor is ok?

hmmm back to the drawing board for improving my gas millage
