We won't be much help. This forum is for camaros and firebirds made from 1982 to 1992. While there are a lot of similar concepts we don't have any information for your vehicle. Either go to a Nissan forum or take it to a shop. My suggestion, take it to a good shop.

A P112 code means thirdgen not found.

I have no clue what a Nissan Quest is, but I can advise you to not take it back to whomever buggered it up in the first place.

I feel like Google p1126 should have been your first action
