HOW BOUT THE INFO ON CAUSES OF P2196 PLEASE! rumor has it that o2 dont fail rich.
I'd recommend starting a fresh thread, this is informational only.

In your case, I'd examine wiring to/from the O2 sensor to verify it isn't in some way damaged. Once that is verified good, you have to assume that either the sensor is non-functional, or it is actually reading rich due to a tuning or mixture problem elsewhere.

I'd recommend working with somebody experienced to examine the car.

Wow this thread is helpful haha, but when I set it up to the computer it came back with PO602 an 605. Any suggestions to fix this? The check engine light was on, but after I took out the performance chip it was off again but I drove probably another 100 miles and its now back on. My car's power seems really low also and kinda stutters or hesitates during high rpm's.

Thx for the help guys

I just got a 2195 also. Called the dealership and they said:

O2 Sensor 11 indicates lean.
Sensor not switching properly. Should be switching rich / lean / rich / lean but instead indicating lean. Tech told me the most likely cause was a vacuum leak.
