Chevy 5.3 My oil pressure gauge reads 0 and the Oil
Pressure Low Low light stays on and beeps the whole
time I drive it. I replaced oil pressure sensor/sending unit
and it stopped and oil pressure was normal for about 4-5
months but now it's doing it again. I replaced it again and
it did nothing. I see on here where people are saying there
is a filter I can remove that gets clogged some times.
Where is it located and is that my problem?
This could be the problem, and you were already there. The screen is under the oil pressure sending unit, and it needs to be fished out and cleaned. That is if your vehicle is a 2007 and up model year.
