Had my ugly little yellow dash light come on the other day and had it scanned, it came back with a p0160 heater oxygen sensor bank #2. Is that the pass. side before cat? and where can i pick on up pretty cheap...

 

they have some pretty good prices and i'm not sure which one it is...i got the link for a 2000 4.7 not sure what you have...you goto emissions, then oxygen sensors though http://www.rockauto.com/catalog/raframecatalog.php

edit:guess it just takes you to their site but the link will get you taht far

 

Ah ok, I got mine even cheaper then that. I paid $51.43 for mine and it was NOT a universal type. I got family that works for DSW (Dealer Service Warehouse) they supply parts for repair shops and car dealerships. and I can get their employee discount, Which is usually 10% better then wholesale, so i can usually get stuff cheaper then what the shops and dealerships pay.
