02 Sensor Problems

[edgy77]

Hi,

I have a 2001 Audi S4. Tial 605s ect ect ect. I replaced the Bank 2 Sensor 1 02 sensor. I am now getting two codes, about 50 miles after replacement. the codes are P1120 and P0154. I checked to make sure it was plugged in all the way. Check the connections of the plug. Now I'm lost. Anyone have any idea of where i should start? Bank 2 is the drivers side correct?



Thanks ahead of time.

you did replace the first O2 sensor right? the one closest to the head, not the one under the car.

Yea. I replaced the one thats a pain to get to right behind the turbo. About to order another one. Maybe the one i got was a dud. Ive had that problem with this car lol. Parts never work the first time.
