o2 sensor stuck rich?
i have a CEL code right now that reads P2196: o2 sensor stuck rich. i want to get this fixed asap, but im not sure how to do it. idk if its the sensor on the down pipe thats stuck or the one on the s-pipe. i do have an exhaust leak from the downpipe to the s-pipe, idk if that could be causing the problem. i was wondering if anyone knew anyother possiblities that could be casuing me to get this code. and how to go about getting rid of it....hopefully i dont need to buy a new sensor cause they arent cheap.

Because the first 02 dosnt measure richness, the 2nd 02 measures weather or not your vehicles cat is working properly, and will throw a code if it believs your car is running too rich or the cat is not working as designed.

hmmm you think it may be thrown off from the exhaust leak...air and exhaust gas escaping before it reaches that sensor? ive had the leak since the kit was installed tho and this is the firstime ive thrown the code. is there a way to check and see if its damaged?

i thought the cat code was a differnt code all in itself, P0420 Catalyst efficiency below threshold isnt that the cat code? sorry for all the questions i just wanna make sure that if i ignore this code it wont cause anyproblems. thanks for the help too whocares, i appreciate it.

it came on while the car was in closed loop, i did hit full boost before that tho, whe ni gothome i let the car idle for a while before shutting it down and thats when i got the CEL.... lol

I've been running with that CEL on for oh, 9 months.. Lol.
It's ok but you run rich as heck - so you waste gas.
I probably woulda saved more than the o2 sensor's worth in gas if I had changed it right away.
