A P0051 and P1168 were read.
Turns out that having a speed bump made of ice in your driveway thats tall enough to scrap the bottom of your car is bad.

My question is does anyone know what the P/N of this particular A/F sensor is?

Car just broke 21k miles.

 

if i'm not mistaken those codes are for your oxygen sensors, just google it you can pick them up cheaper off the net anyway. i had the same problem and it turns out the wires got ripped out of the right rear sensor. you can see it if you get under there and look. stealership charged me $325 cuz i was too impatient to order it and do it myself...

 

Yep, you are right, its an oxygen sensor. Now to find a P/N....
