Why would the test show that some items are not supported like heated catalyst , on 2002 Chrysler PT Cruiser

Heated catalyst , secondary air system, ac sys refrigerant?

Asked by for the 2002 Chrysler PT Cruiser
If it says ' not supported' , it means the system is not equipped with that item. Not all emissions systems are created equal.
Thank you, it seems my egr valve is not switching on and the cat converter isn't reading so I tried driving it but didn't help so I need other options drove it on freeways and streets.
