This is not that uncommon. The temp sensor is basically a thermal resistor whose impedance changes with temperature. Typically a high impedance equals a low temperature reading.
Either the sensor went bad, or your connector is open. It's not hard to replace or check. Do a search to see the posts on others that dealt with this issue.

i 2nd that notion...where do we find these connections? i'm experiencing the same issue and have had NO luck searching in this forum for an answer to it's location. I'm 
(read: all ears), lol.
Thanks in advance!
FYI - now driving an 01 if that matters!

Find that thing, and let me know the next time you are in San Diego, and beer on Coronado Island is on me!!

From the mechanical diagram of the engine, the oil temp sensor is located immediately above the oil filter on the driver's side of the pan towards the rear. You should see what looks like an upside-down "T"-like fitting with 2 bolts on either side that bolts onto the side of the pan just above the filter with the sensor plugged into it from the top.
If it's disconnected, then you've found the problem. Otherwise, check the connector for a problem and clean the connector to ensure it's making a good contact. The connector has 2 wires (Dark Green w/White Stripe, and Black). To check if the connector is good, with the ignition ON (not running) if you take a voltmeter and measure across the connector pins you should see ~ +5V. If you get 0V, then there's an open circuit in the connector wiring somewhere.
If the connector measures OK, then the issue is likely with the sensor itself. It's not hard to replace, but needs to be carefully torqued (15 lb. ft.) as it's been known to crack if overtorqued.
Hopefully it's just the connector. Let us know what it is.
Thanks for the beer offer. I haven't been to SD in a few years, but always love it down there.

Thanks a ton. By the way, the longer you wait the warmer the beer gets!!
