"One of the three" catalytic converters? There is only one. They want to
sell you a "rebuilt" unit? Run, do not walk, from this place. I would guess
you have an O2 sensor about to go, probably time to change all of them.
Often an intermittent CEL will indicate a minor emissions fault, which isn't
critical to engine operation. A failed cat means you will hear the element
rattle inside the housing.

Anyway, find someone else to check this out.

It has three cat converters and reman units are available.

It would probably be a better idea to see what codes are stored before
replacing all four O2 sensors. Pretty expensive guess if you ask me.

If it was originally sold in California, then yes.
