Also, if possible, check this AFM filter at each oil change until you understand how well your engine is maintaining the cleanliness of the oil inside it.2
2007 Suburban with the 5.3L. The oil pressure gauge read at good levels until it was warmed up, then randomly would drop to zero, even though the engine sounded fine with no signs of low oil pressure
The 5.3 engine is not the cleanest engine in the world when it comes to oil for a few reasons.

The oil was very dirty and the oil change place had put in a very cheap filter, so I decided that it couldn't hurt to try that before we go dropping oil pans and replacing pick-up tube o-rings and all
And you damn well better replace if going through the trouble of replacing the oil sending unit
Installing the oil pressure sensor (which you might as well replace as it is a high failure rate item) will insure the filter is seated properly
I would recommend replacing this if replacing
Recommend replacing when performing oil pressure sensor at the same time.

This cured the loss of oil pressure problem at the gauge in my 2010 Suburban
Fixed my Suburban's fluctuating oil pressure problem
Worked great to fix my low oil pressure problem
As such, the main engine oil filter can clog and go into bypass mode which sends unfiltered oil into this new AFM filter and your oil pressure gauge may indicate an oil pressure problem with or without ODB2 codes
Since then I have run it several times, and so far no more oil pressure problems
