check engine light (auto, air bag, MPG, truck)

[twilight61108]

So my 2007 nissan sentra check engine light on. I had the code read and it was p00031. is there a sight or something where i can look at that code to found out what it means???... Okay so i found info suggesting its the front o2 sensor which i believe since i had this problem last year!!! except then it was covered by a warranty. Any one have any idea how much this could run me?

I dont know what model Sentra you have (S? SE-R?), but here is a o2 sensor (front or rear) for around $30.

I have a 99 Tacoma SR5,bought new,after a couple of years light came on and stayed that way for 5-6 years.Eventually I got curious and it was for side air bag which doesn't exist,module reset and o'k for a year.Light still comes on & off,someone said put black tape over it!! Just returned from CT,average mileage,26-28 MPG so will not worry about light.Dealer charged $80 to reset module.

A 99 Taco doesn't have a passenger side airbag? Find that hard to believe as I believe that has been mandatory since 1995.

According that that, you have the only one without dual airbags.

Hey, as long as nobody gets served up a facial of some sorts because of that, do what you must.
