Most important thing you need to do is to establish the actual oil pressure. put a mechanical gauge on the engine and read real oil pressure. If pressure is low (min is 15psi, I prefer to see at least 20 at idle) there is an internal problem...bearings etc. If pressure is good, sending unit has failed...replace it. I would not drive it 'till the oil pressure is verified as being safe. You might get lucky and someone just forgot to plug in the sending unit, but it must be checked!!!

Sounds to me like the Throttle Position Sensor. Thats usually what makes the throttle "rev" But that is not going to make the oil pressure drop. Pull the codes from your car and look them up online. sometimes there is an extra fuse u can add to your panel and turn the key on and it will flash your codes via the check engine light. i.e. if the light flashes 2 times then small pause then 1 time and long pause that is code 21. if there isnt a extra fuse you can usually jump it with a paperclip and pull the codes. not really sure how to do that with yours. but im positive Google knows ;)

That is normal, my truck , if it had a light , it would be on, the gauge goes to about 0 when idling and flies right back up when going, When it stops moving is when I'll get worried about it. You might try heavier oil this summer and see if that changes anything. Go with a 10w40. If you are already using this, try straight 40 one time. Hope this helps.

Testimonial: "Thanks for your help"
some cars with oil level warning light on, it doesn't mean that its only reading the engine oil level is low, sometime the transmission fuid too. Did you check your transmission fluid if it is ok or not? try to check and let us know, ok.

Exhaust pressure sensor a possibility if it has a DPF (diesel particulate filter). Has it had its fuel pump recall, the oil pressure light could be just the constant cranking and running the battery low.
