Where is the CAM sensor located on the 04 Neon? I've been having problems with the check engine light coming on and the car not wanting to go above 2200 RPM. After taking it to a local auto parts store they said that the CAM sensor needed replaced. My husband said no problem and bought the part. Now we have no idea where it goes. Any ideas?

2004 Dodge Neon 4 cyl Two Wheel Drive Manual

I have a 2004 Dodge Neon SXT, 2.0 SOHC, Manual transmition. I have recently been having issues where The car will sputter out when driving, and the check engine light comes on. By sputter I mean, when I go to take off in first gear, I get up to about 2500 RPM, then it sputters like there is no fuel going through the lines. Switch gears, and again about 2500 RPM give or take, and will continue this for each gear. Or when it chooses to work correctly. Lets say I'm doing highway speeds, it will cut out, as if no fuel. Let off on the gas, and wait till I'm down to say 30 mph. Then kicks back in.

I was assuming maybe something with the fuel pump, or fuel filter. But apparently there is no filter on this car.
Currently the check engine light is off. But I decided to hook it up to the computer and analize through this method.
I came up with 2 codes that say the same thing. Camshaft Position Sensor Interupped.

I've located the part on the car. But haven't gone any further.

Could you Please advise me as to if this is the problem?

Hi, I have the same exact car that had the same exact problem. It is the camshaft positioning sensor and it either had fluid leaking on it or it needs replacing. Mine needed replacing period. It is a pain in the neck and butt to get to but trust me it will fix the problem.

Also, if you find that the positioning sensor is fine, check the wiring, if any fluid touches the wiring, it's shot.

2004 Dodge Neon 4 cyl Front Wheel Drive Automatic

I have a 2004 Dodge Neon. My engine light came on and I used my diagnostic tool to retrieve the trouble code. I got a P0340 Camshaft Position Sensor Circuit Malfunction. There is no Haynes Repair Manual for this car. Where is the Camshaft Position Sensor located so I can replace it?

A few weeks ago I replace the cmp because a got an check engine light. The scanner said it was the cmp sensor, but now I got another code ( p0344) which says " rationality error detected for intermittent loss of camshaft position sensor" what d u think that could be? Do u think is because I only replaced the cmp senor but not the cmp sensor target magnet? D u think that I could damage my engine if I dont fix it soon?

This can be because the timing belt is wearing out and let the engine jump tooth or the connector is bad. Here is the location of the sensor and connector. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

I just bought this car two days ago and the check engine light came on. I went to Advanced Auto to have it checked and I was told it was the Camshaft Positioning Sensor. The part is cheep. And I know a bit about vehicles but I'm not sure about this sensor. Am I able to do this myself? And if so how?

Okay any help would be appreciated, problem is car will not start if camshaft sensor IS plugged in. If I unplug the sensor it will run and run pretty good.I have already replaced the cam sensor, crankshaft sensor, knock sensor, and the PCM. No diagnostic codes come up except the cam code, but thats because it is unplugged. There appears to be a little oil in the intake manifold. No dealers no what is wrong with it. If one of the certified mechanics helps and it actually works I will donate at least $40. II and everybody I know are completly stumped. PLEASE someone HELP!

This is a toughie! After replacing all those parts and still having a problem I would say you have a electrical problem in the wiring harness. Pull back the tape and covering especially right there where the wiring comes out of the harness that goes to the camshaft sensor. Neons are bad for worn open wires in that part of the harness. You may have a burned or worn wire causing the car to run when disconnected then once plugged in it shorts out making not able to start. Also check the plug going into the camshaft sensor for damages as well. Make sure there are no prongs damaged or any problems that could cause a short as well. My best guess is you have a wiring problem. Hope this gets you in the right direction. MORT
