I have a CEL and so I went to Advanced Auto and had them scan it, they got P1122 and P1140.

I've searched the forums and google and I get different descriptions as to what the codes mean. Will someone give it to me in layman's terms? I don't know much about 'wrenching' but I'd like to learn.

Is this a simple fix and if so, can someone please guide mein the right direction?

you just need some new o2 sensors which you can get from www.vastperformance.com

 

i went to the site and found oxygen sensors and widebandoxygen sensors... i'm assuming the regular one is ok?

how difficult is install?

You can select either front or rear sensors, you need front (pre-cat) which is bank 2. Replace both sensor 1 and sensor 2 while you're doing it since vast sells them in pairs.

 

seems like i can fix both issues by replacing the rear o2 sensors...

iread it's easier to fix the rear sensors as they are visible and easy to get to...

do you happen to know of a DIY guide for this sort of replacement?

 

Bank 2 is the front or pre-cat sensors. Replacing the rear won't do anything, but yes they are easier to replace.

 

not first O2 sensor but second and its the heater side that's gone down ( HO2S ) BANK 2 SENSOR 2, check for burned/broken wires to that sensor

 

probably best to just have the shop do it then if it's the front ones

 

How did you ever make out?? I have the same codes.... does anyone else have some input?
