It *should* not.  The oil pressure sender is simply a switch that opens
when a certain pressure is reached in the system.

No.

Unlike a light bulb, an LED will glow faintly with a very small
current.  Moisture, particularly salty moisture on the outside of the
sender could allow this.  The connector has a rubber boot that's supposed
to snap on and keep the connection dry, but by this time it's probably
split or gone entirely.

However, it's also possible that the sender has an internal fault, either
moisture gotten in from outside or a tiny leak in the pressure diaphragm
which will get worse with time.
