I have 2007 Silverado 1500 ltz, a few months ago my dash message popped up saying “engine oil low add oil”

since this has happened I have changed the oil, replaced the oil pressure sensor and sensor screen,
replaced my oil pump, and re-replaced the pressure sensor and sensor screen.

after the last sensor and screen replacement I unplugged the battery to remove the “engine oil low add oil” message and it went away, for about a day... I was driving today and the message appeared again and I cannot figure out why, I have plenty of oil, my pressure reads right at 50 psi, I don’t hear any ticking under the hood or anything.
However when the oil pump was replaced the timing belt was not, I’ve heard mixed things that those two items usually go hand in hand? Dunno how true that is... any help?? Kind of in an emergency situation here, after the pump was replaced I drove all the way to Minnesota from Virginia Beach (1400 miles) and no problems, no messages or anything, concerned about driving back though now that I’m getting the message again.

Timing belt won't have anything to do with this.
