I'm getting an error code from my 93 cadillac seville P040, can anyone tell me where the power
Steering pressure switch is located?

On my 88 Allante it was on the steering rack itself between the 2 hoses to it. Remove the electrical connector, clean it apply dielectric grease to the connection and plug it back in. Clear the code. Report back if necc. That sensor reads pressure in the steering rack when the wheels are turned and raises the idle slightly to handle the extra load on the engine.
