engine light came on today with code P2195. I know i had work done on the o2 sensors a couple years ago but i’m not sure if they were all replaced or which was replaced. i hear the slightest whistle in the engine bay but can’t really pin point it. somewhere near the egr valve (which i replaced last summer). idle is very slightly rough. any ideas?

FWIW
If replacing the O2 Sensor doesn't work
Inspect the
Intake Air System Components
Clean the MAF
Put a Fuel Injector cleaner in the gas tank or replace Injectors
Check for exhaust Leaks

turned out to be a vaccum leak in the hard plastic hose that connects to the air intake
