The 2003 Cadillac Deville oil pressure sending unit is located on the left-hand side of the engine. The oil pressure sending unit will be three inches above the oil pan.
on the side where the oil filter is located
Oil pressure sending unit is located by oil pan in front. Unplug unscrew and install new one
Drop the fuel tank. Remove the fuel pump and sending unit assy. This is incorrect, the 2000 up deville has an access plate in the trunk, pull out the mat and it will be obvious you can change full sending unit and pump through it.
Yes, oil pressure switches are located on the side of the oil filter adapter housing.
I've repalced a fuel pump in a 94 Cadillac STS and it required removal of the gas tank. The sending unit is on top of the tank.
On the backside of the engine drivers side closest to the fire wall.
Lower the Gas tank. Remove the sending unit/fuel pump from the tank and replace the unit. The sending unit and fuel pump come together.
It can mean you have low oil pressure and it can mean that the oil sending unit is bad. Do not ignore this and have this checked out by a trusted mechanic.

Check oil pressure with a manual gauge. Could just be a bad oil sending unit or low oil presssure due to internal engine wear
Hey Oscar- this happened to me too, I replaced the oil sending unit on the bottom of the engine just behind the passenger front wheel but behind the engine. This will fix it.
