When I replaced my engine 2 years ago, I installed a new oil pressure sensor. Over the last month or so I noticed my oil pressure gauge was kinda showing low, and then the gauge would go to 0 and all the warnings would go off. Of course, I stopped to check for issues. I decided to change the oil / filter, and found no metal flakes nor did the engine make noise while this happened. It would go days with no issues, then it would happen again, showing no oil pressure while driving. Finally I got P0521 confirming I don't have an engine problem, but a faulty 2 year old sensor. I replaced it and all is good!
