This could be a number of things but the likely issue is a faulty sensor. Did the pressure come back up or is it still staying low?
We should start with checking codes because this could be a circuit issue. Here is a guide that will help with this:

Also, here is a guide that helps in general with this issue of low oil pressure:

We need to also hook a gauge to this engine and see if the actual oil pressure is low.
If it is low then we don't want to drive this vehicle until we fix this. However, if the gauge shows good pressure then we have a sensor or wiring issue.
Take a look at the attached below for the detail on how to run this test.
