when do the code come back after you drive or when the engine is running or key on ?

Expert:  Clifton B. replied 1 year ago.

you have the right sensor for the code so you most have a wiring or computer problem

Can it be grounding issue because I took car took Nissan dealer and they said it could be fuse, wiring, valve witch I replaced so its not that and they also said grounding issue
Customer: replied 1 year ago.
I checked ground cleaned it up but still the same
Customer: replied 1 year ago.
If I do hole new grounding kit would that make it better or I would have to find original grounding wires if so where are they located in case I missed some
Customer: replied 1 year ago.
I changed computer as well and that did nothing so the only other thing is wires a guess
Customer: replied 1 year ago.
I did check wires from valve harnes to fire wall and they fine but it goes thru fire wall in to the car what possibly can go wrong there unless there was water or fire in the car lol
