Idle oil pressure and pressure sensor info

2004 Colorado 3.5L with 54000 miles. Car out of warranty.

What is the oil presssure specs and at what pressure does the oil light come on?

Background: While doing the recall, I had the oil changed. A week later the oil light comes on only at idle. I check the oil level and it is way too high. Manual says high oil level may cause damage. I drain about a quart out and it still has low oil pressure. I put the oil back in, take it back to dealer and explain the problem. They drain some oil out and see the light still comes on. Now they are saying it is the pressure sender. I am gonna leave it with them and see what they come up with. Just trying to get background info so I can tell if they are fibbing or not.
