Default P0240 Code

Hello friends. My check engine came on the other day. It threw a code of P0240. Is there any other way to fix it before changing the catalytic converter? Any help is greatly appreciated. Thanks!

The link below has the list of possible issues, but for Camry the odds are it is the converter.

I had that problem with my Toyota 1995 Camry 195000 and 2003 Suburban 175000 My air intake butterfly was not working properly. Cleaned it, all is good.

Can remember what I used but it is for cleaning the air intake and try not to shoot inside. Also some air intakes are manual where you can move the butterfly and clean while my suburban is electronic and must be moved by pedal. It's been a while but those are the key points. Mine was filthy. If butterfly is not working right the air flow could be all messed up and hence the fuel flow. Simple first
