2010 Honda CRV oil pressure light comes on and goes off what could be the problem?

Since buying this car I have had some random issues, the AC went out then the VTECH had to be replaced. Recently my malfunction light came on and I had it checked by big O tires with their computer and it came back as a Cadillac converter problem I took it to Honda dealer and they said that I shouldn't worry about it couldn't go off on its own it did but now as I'm driving if I accelerate or break too quickly or even come up to a sharp turn the oil pressure light comes on and then it will go away. My vehicle still has a platinum warranty as it was certified pre owned but I have until next year or until I reach 100,000 miles and I'm currently at 91,934 does anyone have any ideas?

It's a catalytic converter possibly you have oil that is too thin or a blocked oil filter or low oil, get the oil and filter changed and use only fully synthetic oil at least 5-40 or 10-40 and see if the problem goes away if it doesn't it means bearing or oil pump problems and that's a lot more expensive

Your oil light could be a defected oil pressure switch if the oil level is full and the corrected oil is used. About the Catalytic converter (CAT). Check with Honda, depends on which State you're in, the CAT cover goes for 7 years or 70,000 miles. Or check into the manuals for details.
