4.2L O2 sensor location
Hi Folks
Have fault in bank2 sensor 1 (upstream?) Mechanic that inspected it said bank 2 is driver side and bank 1 is passenger side of vehicle. Parts store guy says it's the opposite. So who's right? Thanks for the help

Unless I am badly mistaken, Bank 1 is the side with #1 cylinder.
In the case of the 4.2, #1 cylinder is the front cylinder on the passenger side.
To verify, you can always look at the coil pack, find the #1 wire (connections are numbered with small numbers molded into coil pack assembly) and follow the #1 wire to the #1 cylinder.

if it ain't broke, don't fix it
If money's tight, all you need to replace is the one throwing a code. I would bet that is why he wanted to know which side is which.
