Front O2 Sensor Bank question
Which sensor is the Bank 1, Sensor 1-B? Is it the front drivers or passenger sensor? Did "search" but no help.
Also, how easy to replace? I know the location, but will it require that I drop the exhaust tubing down to unscrew and unplug the sensor? I'm having code issues with this sensor and in my process of elimination, the next step is to replace it.
I'm getting codes issues P0133 and P1134. Already checked fusing.
Thanks for the help

Bank 1 is the drivers side, bank 2 is the passenger side. Sensor one on both banks is the primary O2 and sensor 2 is after the cat to make sure the cat is working properly.

Thanks 5 Liter.
Anyone have comments in regard to ease of replacement? Or comment on the particular codes I'm getting?

The primary O2's are in the exhaust manifolds, not sure how hard it will be to get one out. Probably a little tight in there. The secondaries are in the center section of the exhaust. They are a snap.

Re: Front O2 Sensor Bank question (LV)
they are easy,just make sure you don't use a open end wrench.get a 02 sensor socket or wrench[the size is 7/8"].also a shot of pb blaster[rust spray]will help in getting it loose.it's tight,but not as bad as it looks.

Re: Front O2 Sensor Bank question (LV)
unless you have a air leak right in front or in back of the o2 sensor,it sounds like the o2 is bad.both faults you have are for a lazy o2 sensor[it' not switching between high/low fast enough].

Just changed both my fronts this afternoon it is easy. Make sure you have a short wrench.
