Good afternoon,

You have two issues.

https://www.2carpros.com/articles/high-oil-pressure

first, correct your oil level. You should check it regularly so it never gets that low.

Second, there is a pressure regulator in the oil pump that regulates the pressure. If it is sticking, it may not release and the pressure will go high.

You should have the pressure tested manually first to be sure the sender is sending the correct signal.
