oxygen sensor failure
 

Hi all,
I have read all the posts on code p0133 for oxygen sensors and my question is could a leak in the exhaust cause this code to go on. I know it happens with vaccum leaks but i noticed a small leak at the connection of the cat converter, would this trip off the oxygen sensor lambda light?

thanks in advance

Yes it can if the leak is big enough.
