left bank vs. right bank
 

O2 sensors are designated front or rear bank and/or left or right bank. on the 2002 Galant 3.0 v6, is the front bank(closest to the radiator) the left or right bank?

the front of the engine has a cam belt, the rear has a gearbox attached.
Engine left and right usually designated looking toward the front of it, with no1 cyl being front left.

are o2 sensors and lambda sensors the same
