Alright Im getting as low as 17mgp. I had check engine light show o2 sensor change on 10/06. I didnt find out which 1 cause it costed a lot apparently. but now nissan cant tell me which o2 it is. My engine light is on but instead of finding out which o2 it is, Ill change all 3 myself.

SO I got these part #s for my 95 maxima.

1.22690-0000u06 likely front o2
2.22690-0000u16 likely front 02

3.22690-0000u61
226A0-0000u61
4.226a1-4L715 WTF??? Is this the 4th o2 for Cali specs??


Question is will I need my ECU reprogrammed?? I thought it only needs reprogram if using NEWER UPGRADED o2 sensors. let me know.

 

No you don't need to reprogram your ECU, all you might have to do it reset it. Which is just removing the battery.

 

Awesome. Thx White

 

Why don't you just check the codes and see which O2 sensors are bad? And when you find out which ones are bad, change the ones in question.
