Try posting why you ask this first
my guess, dash CEL glows, driving,
guess 2, you get it scanned and it shows a DTC error you forgot to tell here, then assume its a bad part, named per above.
why?
first is to get the gas cap tight ( or new)
and then push reset on the scan tool.
then see if the undisclosed, DTC errors, goes away.
this is first. all cars 1996 to NOW.
unless building a EVAP leak down test system is fun. or easy.?? or guessing all parts in the system? why"
