I have a jeep 2007 with 85000 miles. Recetly purchased it from a dealer. What happens is the oil pressure light comes on occassionally. This happens after the jeep is turned off and then restarted while still warm. Such as when gassing up or a quick stop. If I turn off the jeep and then turn it back on the light turns off. I have checked the oil and it looks to be a the correct level, it is clean and recently changed. There is no noise associated with the light and the engine seems to be running well. Again this has only happened a few times and is not consistent. I am leaning towards a possible sensor issue.

It could be the oil sending unit...or you may indeed have an oil pressure issue...kudos for you knowing WHEN it happens. But don't risk on "leaning" cause it could cost you $5,000! Anyway, have a shop you trust (or do it yourself with a $15 tester from harbor freight) check the oil pressure under the SAME condition you described and check the oil pressure that way...good oil pressure = bad sensor; bad oil pressure = oil pump issue.
