Just so I dont get the wrong side...
The code I got was for P1115 which is the os2 ahead of the catalytic converter for bank 1 (which I'm guessing is cyl 1-3)
Are all of these adjectives referring to the same o2 sensor position?
in front
ahead
precatalyst
part #15182 looks like it would be that (above)
part# 15183 looks like it be would described below
rear
behind
postcatalyst
I don't really see why the price difference is so much for the other position.
