My Cavalier (195000 miles!) keeps getting error codes indicating the rear catalytic converter warm up time is too long. At the moment my brain is blank trying to recall the error code number. Anyway, I reset it and it comes back the next day. So, I think I probably need a new catalytic converter and O2 sensor for the car.
I see AA and AZ have the direct replacement CC’s which would be pretty easy to install. Are these decent CC’s or should I look elsewhere? They are not too expensive.
Is there any way this is only an O2 sensor problem? Can AA or AZ check the output voltage of the O2 sensor and tell me one way or the other?
Thanks!
