Have a shop verify the pressure is really low, it could just be the sending unit is defective for the oil press guage, but get it checked, if it really low you could burn out the bearing in your engine, a very costly repair.

This is normal. On your car, on a cold start the pressure will be around 75 PSI. After the engine warms an oil pressure of 15-20 PSI at idle is just what it should be. The oil pressure gauge should escalate when accelerating up a bit to. If your old school like me 15 PSI mean danger but tat Caddy is just fine.

When the engine and oil are cold it will show a high pressure because of the viscosity of the oil. When it warms up the oil is thinner. If it doesn't drop below 20-25 psi at warm idle I wouldn't worry about it as that is normal.
Very first thing you need to do is install a mechanical pressure gauge on there to verify what you see on your gauge. If the actual pressure is low, then it's time to start looking inside the engine. If not, then you need to trace out the electrical problem but will know the engine is safe.
First we would need to know when this occurs.
Asuming the oil level is at the full mark!. If the pressure goes up
during acceleration and down at idle when engine is fully warmed up,
then this is normal. An engine requires 10 psi of oil pressure per
1,000 rpm ( ex. 20 psi at 2,000 rpm, 25 psi at 2,500 rpm, and so on )
. If the gauge is moving back and forth erratically at idle , i would
say the gauge is bad. If it drops to 0 while accelerating I would say
your oil pump is bad. If from time to time it seems to work and other
times it seems not to work, I would say the oil pressure sending unit for the gauge is bad.
If the pump failed you would start to here a
Knocking noise from the engine in a short period of time. Use the
above scenario's to narrow down what it may be.
u Have a problem with the oil sending unit. The sensor is located beack right side of the engine block. Take out the switch and make sure u have good oil PSI. Should be 6 psi at idle and around 50 at 4000 RPM. If the presure is ok replace the switch they are very cheap about 20 bucks. Please rate.
your oil sensor comes on at less than ten psi, you may have internal engine damage how many miles on engine, any gum up inside engine, you can try to put on a high pressure high volume melling oil pump to try to help for the time being, but you may need to have it torn and repaired.
The check gauges light is normal because at 400 rpm it isn't running fast enough to build sufficient oil pressure. I am guessing maybe a vaccum leak???
When the gauge is at 0, is there any noise from the engine (tick, knock etc?) I would have someone put a mechanical gauge on there and read true pressure.Your driving pressure seems OK but if the low number is "real" something is wrong!
