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.
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.
cam sensor o ring replace. check this before oil sending unit replacement.
I have had our 2001 Dodge Neon for about 5 years and it's been pretty good however it has always had a small oil leak but unfortunately it has gotten worse, so to the point that I am forced to have the rear main seal replaced at 450.00 and while I am at it I am going to replace the valve cover gasket, because oil is getting on the spark plugs. In my option this is cheaper than buying a brand new car. I truly enjoy this little car as old as it may be.
the cam senser was cracked on all four corners when car was ideling oil was running out top of cam position senser
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.
