sakataj Posted June 14, 2008 Share Posted June 14, 2008 for the most part they help regulate your emissions but they will affect your gas mileage if they are bad! did u use oem ones whenu replaced it at 50k? yeah u can use a o2 simulator and have the code scaned out or u can fix it and it will go away!

djspawn00 Posted June 16, 2008 Share Posted June 16, 2008 Don't waste your money at the dealer. Changing your 02 sensors is just like changing a very expensive light bulb. You can order replacement sensors from rockauto.com (pm if you want a 5% off coupon code) I suggest you stick with denso as far as the brand goes. If you can post your codes that you're getting I can probably direct you to a tutorial that shows you how to change them. Quote Link to comment Share on other sites More sharing options...

I usually stick with an OEM manufacturer where possible. Quote Link to comment Share on other sites More sharing options...

I usually stick with an OEM manufacturer where possible. I just had a sensor go bad - bank 1, sensor 2. Ordered the O2 from Rock Auto - Denso P/N 234-4622 which showed for forward lower. The wiring harness is no where near long enough - about 14" shy - at least on an 03 GS300. Anyone else run across this problem? Quote Link to comment Share on other sites More sharing options...
