Oil Pressure Light On?
I have a 99 Prelude base model. The oil pressure light stays on saying low on oil. It has plenty of oil and oil pressure. I changed out the oil pressure sending unit still no luck, and put a gauge on the sending unit. Has this happened to anybody else.

Do you mean you checked it's continuity to ground with a multi-meter?

I think the pressure switch is normally closed. It opens when the pressure is good. So it would be a short-to-ground in the sender wire. If that's it, the idiot light would continue to be lit up if the pressure switch were unplugged.
