I know the locations of the sensors I need to replace and I know the codes:
P0138 and P0158, the thing is I am getting the parts from Autozone and they do not list the banks or anything they say right front or rear so I was wondering if anyone can help me find the actual part for my sensors so I can take care of it.
This is what I am referring to:
http://shop.advanceautoparts.com/web...=oxygen+sensor

the location says "•Oxygen Sensor Universal Fit - Upstream;Two required;24 V"

so I dont know which sensor I am replacing.

 

those are universal meaning you will have to splice them into your current wiring harness. i suggest getting exact fit, and when you do so, the front 2 sensors have the same part number. i believe the backs do too, but not positive on them

 

I spoke to an agent at Advance auto parts and he gave me the following links to replace my sensors and what parts would it be.

Location: downstream rear

Location: upstream
http://shop.advanceautoparts.com/web...932%7CL2*16465
Location: downstream front

There is a diagram on this site I added below that should help. I replaced just the upstream rear and it was Bosch part #13350.

I'm only mentioning this because I used them for my O2 sensor, but there are a lot of Advance Auto coupons you can use to save a lot of money if you order online.
