My 1997 Pathfinder and my co-worker's 2002 Maxima both have had chronic CEL coming on issues - and on both vehicles the code clears when it is run on good quality premium gas.
My code has always been P0156, and despite 11 visits to Nissan Dealerships, it has never been fixed properly.
Anyone else have any similar tales?
I have read something about Nissan oxygen sensors being sulfur content in gas finicky!
FG.
