I have been retired for 12 years but when working, I became very proficient at obtaining all the readiness codes on the 993 to constitute “a trip” in one road test (20 minutes or so). A couple could be triggered with the PST and the rest were fairly simple and required no abnormal driving. We had a list that specifically spelled out all the parameters.
BTW: Secondary air injection ports being clogged was a common culprit for CEL due to worn valve guides on the 993.
