My engine light just came on with the code P0320. on 2004 Hyundai Santa Fe

Which says Ignition/Distributor engine speed. The guy asked if I've been having trouble starting or running rough, not been a problem, car's been running & starting fine. Do I need to run to a repair shop immediately? What does this code really mean?

Usually the ignition failure sensor, reads if the cylinders have or have not fired on time, also is used for the tach operation.
Thank you ProfessorG - is this something I need to run in with?
It shod be checked. If you leave it alone you could be left hanging.
