Question about 2005 Dodge Neon SXT
Changed the sensor two different time and still the same results
Installing parts based on a code is not how it is done
The codes do not tell you what is wrong or what to replace
PO344-Camshaft Position Sensor Circuit Intermittent
The sensor just reported a fault code,now you need a shop
with trouble charts to properly diagnose the issue
Could be mechanical

SOURCE: 2004 Stratus 2.7l bucks above 2000rpm runs fine below 2000rpm. MIL P0344 is set, changed sensor reset code and it came back, unplugged sensor and tried starting the car. The car started after 8 second
Did you check your camshaft position sensor circuits to see if they were working correctly or test the sensor itself before going out and replacing the sensor?....Didn't think so....
Lesson learned here? Diagnostic Test Codes (DTCs) DO NOT tell you what parts to replace. They only tell you which systems or circuits in your vehicle are not working as they should be. Then it is up to the person diagnosing the car to determine what is actually CAUSING the system or circuit to malfunction......Of coarse, this requires that you must first understand how the system is supposed to work...
Anyway, with some proper diagnosis, I think you will probably find that your cam sensor code (P0344) is being caused by a timing belt that has skipped a tooth (most likely).
Bad wires or connectors in the wiring harness that is losing contact at times can also cause that code. This can be verified by watching the cam sensor signal to the PCM with a lab scope and wiggle-testing the wiring harness to see if the signal drops out.
The cam/crank sync needs to be checked with a scan tool. If the sync PID is switching back and forth between YES and NO, then it is most likely a skipped timing belt. This is usually CAUSED by a bad timing belt tentioner pulley assembly.
Yup! they DO tend to buck a little when the valve timing is not correct!
