If you are getting a cam sensor code, it is not always the sensor. The code is just giving you imformation to what the ECM is seeing or not seeing.

The circuit needs to be tested. All the way from the ECM to the sensor.

You will need a wiring diagram and an explanation of how the circuit works to properly diagnose the problem.

I have a 2005 dodge neon that will crank but wont start. I have replaced the cam shaft sensor, crank sensor and the coil pack. Iam also not getting spark to the coil pack. Any suggestions?


Primary voltage to several systems, including the ignition coil, dark green wire with orange tracer. That voltage comes from asd relay. There is a fuse for asd relay. To check for voltage the engine has to cranking. The control side of asd relay, the computer has to ground it before it will energize. Did you check wiring circuits for cam and crank sensor connectors before replacing sensors? Are there any applicable trouble codes?
Are you ok with testing wiring circuits?

On a 2000 buick regal 3.8 have a code p0341 changed cam sensor and IGM code still comes back


problems associated with the cam sensor are ---insecure sensor/rotor---air gap---wiring---and the sensor itself. In the workshop manual it will explain how to check the rotor security and the air gap. If all is ok use the code reader to reset the CPU an eliminate the code.

Neon Code P0344


I believe that the splice for the cam sensor is about 8 inches back in the harness. Power to the cam supplies several sensors. I have fixed a few that the splice was bad, There is very little room to work in to get to the splice, but it's not impossible to fix.

2000 dodge neon will not start unless the cam shaft sensor is unplugged


I would go and but a cam sensor from the dealer. Aftermarket cam sensors can be slightly irregular. I had this happen to me with an aftermarket ABS sensor on a chevy. The whole problem was a gap difference equal to two sheets of paper. Whats happening is there is an open circuit in your old sensor that causes the check engine light but the new one has a good circuit but bad reading. I would say that is your problem.

This repair shop says this neon 2.0l needs a cam sensor, bought a new part and bolted it up, i still have the code 0344, misfire detected... also new plugs and wires. any alignment required for sensor? i...


  • P0344 means that the Camshaft Position Sensor is having intermittent disruption.

  • Check the connector real well and the wires for breaks, cracks, bulging wires etc.


  • I think that aftermarket sensors are worthless to be honest. I recommend OEM sensor only because aftermarkets often don't work. So if you bought a CAM sensor at your local parts store then I would take it back and order from Chrysler.

  • A chipped tooth on your CAM sensor can cause this code as well because the sensor reads rotation. A missing tooth of the CAM will give an in the rotation of the CAM.


  • So the first this I would do is check the crankshaft position sensor as a fault from there can effect the CAM sensor too.

  • The crankshaft position sensor is in the engine block behind the alternator / just above the oil filter. See diagram below. Clean it real well and check the wiring.




  • Also make sure you clear the codes after the repair of they will remain. A CAM light does not usually just go away after fixing the reason for that code.


  • Now check the wiring and connector to the CAM sensor reall well and repair as necessary. Now clear the codes and see where you stand. If that light comes back and it is the same code then get an OEM CAM sensor and clear the codes again.


  • If that light comes back again then you will need to pull the timing cover and inspect the CAM itself for missing test.


  • If you have any questions please feel free to ask.


  • If you are satisfied with my help then please do leave a comment so others know of my quality work.

  • Crankshaft location diagram.
  • Pull the connector and the mounting bolt[s] to remove.

I have changed the camshaft position senson several times on my 05 Neon and now replacing it doesnt do any good. im getting an intermittent camshaft positon circuit error. how do I test the wiring and what...


I never had a problem with the cam sensor in my neon, drove it for 10 years. However, the O2 Sensor fault tends to send a signal that a bad Cam sensor is present and if the timing belt is lose or jumps that will send a false code. The timing belt on these uses a spring tension device in the 2000 to 2003 and a hydraulic tension arm in the 2003 and later models. The hydraulic tension assembly tends to hang and allows the timing to be erratic. Not enough to throw it off all the time, apparently when the belt pops it comes free, but that is all it takes to through the cam timing off and that causes the computer to send a fault signal or random misfire signal. Look at the Timing belt after replacing the O2 sensor if the O2 replacement doesn't resolve the problem.

Blinking Check Engine light


This is typically a sign of a "detrimental misfire". A blinking check engine light means DON'T DRIVE ME! You may want to have your coil pack checked, plugs replaced or gapped properly, or wires replaced. Would also have to do with the camshaft sensor causing your timing to be off.
