Hello my name is ***** ***** thank you for your question
The Catt Converter is a major conversion for exhaust gases. Waiting till you loose power could damage your engine. The Catt Converter needs to be changed if you are getting a code for it.
Let me explain it a little better..
You have the exhaust gases as they leave the engine monitored by the upper 02 sensor. Then the exhaust gases go through the catt converter and get converted so by the time they hit the rear 02 sensor the rear 02 sensor has nothing to read. Now if the Catt converter is not functioning properly that means the rear 02 sensor is starting to monitor exhaust gases like the upper 02 sensor before the catt converter. If you allow this to continue, eventually the catt converter will come apart which would cause a exhaust restriction ( the loss of power) which can also damage the engine. So yes you can drive with a Catt converter code, but you want to work on addressing the issue before it becomes a bigger problem.
Do you understand? Any more questions on this?
