Depending on the yr, yes it should. I wouldn't worry about it unless you are having oil pressure fluctuation or you just feel the need to replace it, I always say you can't be peace of mind. Only time its recommended is during engine over haul/rebuild or if you replace the oil sending unit due to oil leaking through the sensor or if it just goes bad, it's not at all uncommon for them to go bad and leak through the sending unit.
