The oil level sensor is located inside of the upper half of the oil pan. The oil will need to be drained and the lower half (black sheet metal) of the oil pan removed. Once removed there are three bolts and one wire connection that has to be disconnected in order to remove the sensor. If memory serves, there are about 16 bolts that will need to be removed in order to get the lower oil pan off. It is best to do this when the engine is cool, to avoid being burned by hot oil. You will need a new oil pan gasket (the factory may have only used gasket sealer but some auto parts stores have an actual gasket available). I've uploaded a picture of the upper oil pan (turned upside down).
Let me know if you need more help. Thanks for keeping me on my toes.
