Well if its the original sensor, they are notoriously crappy. Nissan had the sensor redesigned later;the newer ones look completely different. That's what these car companies get for always going with the cheapest bidder.
I know the old one was mostly plastic and the newer ones from what I have seen are metallic. I had both my camshaft and crankshaft position sensors changed under warranty.
