I change my cam sensor in my Dodge Neon 2002 and I still get the same code which is 0340there was a lot of oil in the plugs when I did change it to and still is kinda is that a problem or what can be the reason. its not starting still
I thought my cam position sensor seal was leaking but after closer inspection I found it to be a leak from the PCV valve which sits just above the CPS. I took the PCV valve out, cleaned everything well and applied a liquid sealer to the PCV and reinstalled. No problem since.
