– Open circuit
– Short circuit to ground
– Mass air flow sensor

A dealer should have and use the special #9637 tool and a PST2/PWIS to check the first 2. Or they can just plug in a new MAF and drive it for a while.

About the only thing you can still check is that the air cleaner is clean.

You buy a used car...things are going to go wrong..no matter the make/model.
