Codes alone will not condemn the valve or hoses. Usually there are misfire codes and mixture codes like po170. The true test is to either confirm a cracked hose or valve or have a smoke test performed by a shop. This test pumps smoke into the intake and then you simply wait for the smoke to leak out where the breach is. Not a tool you average DIY has laying around.
