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
cam sensor o ring replace. check this before oil sending unit replacement.
The radio will cut out and come back on. Stop at a stop light the engine dies and show a p2074 code. After I replaced mao sensor tps sensor and ignition switch. The car would act like it has a miss fire in two cylinders. I pulled the cam sensor and found oil leaking on it. I am going to be replacing the cam sensor today.
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.
Oil is leaking in corner of the engine all the way back to the exhaust manifold causing it to drip on the oil pan
Not sure if car is 220L or 220L DHOC, but this is my problem.
