Throwin codes

[BlueLineFish]

just started with p0456 small leak EVAP system.
also p0522 oil pressure switch low voltage( I believe this is it)

I tried resealing the gas cap for the first code with no success. Going to buy a new gas cap and see if that is it. Not sure about the last code. Oil level is good and oil gauge reads just above the middle at all times like it always does. Any suggestions

If the oil pressure switch has low voltage could that be a bad connection somewhere?

Poss a ground issue or nicked wire. Check your box beside the fuel tank for hoses and fittings leaking. Thats a good start for ya.

Mine's thrown the evap [gas cap] code a couple of times, and all I had to do was take the gas cap off and retighten it and it cleared itself.... hope you figure it out
