Hey Guys got a CEL light tonight , the ford app tells me its something to do with the "regulatory" system but when i pull the codes i get p0520 code.
When looking through the fsm i see a p0521 code for a oil pressure sensor issue but there is no p0520 code. Anyone able to verify a p0520 is a p0521?
