It may be the sensor is on the way out.

It may be wiring to the sensor has broken or corroded.

It may be low on oil and you have the wrong dipstick (or you
may be reading the dipstick wrong; make sure you clean it
with a rag before re-inserting to check).

It may be that the oil has thinned due to a) gas leaking from
injectors and past the piston rings when off, or b) a head
gasket leak letting water into the oil. Both of these should
be obvious when looking at or smelling the dipstick.
