Recently my check engine light came on and when I got it checked, it read out that the o2 sensor (bank 1 sensor 2) was faulty. I believe this is the sensor behind the catalytic converter, correct me if I'm wrong. After clearing the trouble code, the check engine light came back on in about 20 miles. Lately I've also been getting very crappy gas mileage, 11-12mpg on some occasions, but not around the 16-17mpg I was averaging when I got it. Since I'm pretty tight on cash right now, will replacing that o2 sensor now solve my gas mileage issues saving me money in the long run or not, because if it wont have a pretty decent effect, I plan on replacing it in a few months.

 

hey brend2b, you are right about the 02 sensor. i just did mine on sat very easy to change. you can run just fine with no problems. do it when you get some extra money.the 02 after the cat really dont affect the mpg .

 

you also can shop around for the best priced 02 . some great people on yota tech gave me a few places to try. i thought that urd racing had the best price for a denso 02 which is original equipment.and that is a first time fit,no splicing wires.

 

i just noticed you are from nj , im about 45 min from you we mostly wheel and trail ride in the pines, wharton st forest and atco

 

yeah furthest south ive gone is in the woods of the sarco sandpits. i've been wanting to go out to wharton since september. i mainly explore the small trails around me but nothing extreme cause im basically stock, and all of the guys i wheel with seem to always bail out.
