The husband had his oil changed last week at the dealership - they said that he had a leak around his oil pressure sensor. He changed out the sensor about a week ago - but today after driving for about 30 minutes - when ever he stops the oil pressure light is coming on then going off.

Mistake in installing the sensor, grime on the connector?? Any ideas where to start??

 

If the dipstick shows a full amount of oil then low oil isn't your problem. The oil pressure could possibly be low because of a worn or broken oil pump, a plugged oil pickup screen in the engine's crankcase,or excessive bearing wear.

 

Did he add any extra thread sealant on the sensor? It doesn't come with any decent amount IMO from the dealer. Also, did he clean out the sensor connector? That can get filled with oil when the sensor leaks.
