Oxygen Sensor

[Ambrosia]

Hello, I am new, thank you for adding me!!

My Oxygen sensors in my catalytic converter are bad, has anyone replaced them? How easy or hard is it to replace on an Aveo?

I replaced the front exhaust pipe on my Aveo5 and used an offset o2 sensor socket with a breaker bar to remove the after catalytic O2 sensor. It surprisingly came out very easy and to unplug the wire was pretty simply to. The pre-catalytic sensor I have not done so far so someone else will have to chime in with their own personal experience on it.

its fairly simple to do the o2 sensor, if you truly need to replace the CAT its more difficult. get an oem plug in type plug, not a hard wire kit. And you will be able to figure it out.
