Have a 2005 dodge neon sxt, engine lite is on i had the catalyst convert changed i had the 02 sensor,camshaft sensor,crankshaft sensor changed now my engine lite is still on and sometimes i cant go over 60mph if i do/try it stutter and drop back donw to 50mph can someone please tell me the problem,thank you concern driver...

P0010 code is the camshaft position sensor. If this fails the vehicle will simply shut off.

P0315 - Crankshaft Position System Variation Not Learned
P0335 - Magnetic Crankshaft Position Sensor Electrical Error China OBD2 car diagnostic tools wholesale on CareUCar

code p 0340 refers to camshaft position sensor(CMP) sensor A bank 1---circuit malfunction===causes ---wiring---CMP sensor ECM
have the CMP sensor checked / replaced
when you are checking the sensor , turn the engine over and if the camshaft is turning , it is not a timing belt
However if the engine has not had a timing belt changed (requirement at 60K miles) It would be a good move to have it done as it is well over due and will fail soon

sounds to me like it has jumped timing

The first one that I bought was defective. Make surebthe surface where the sensor connects is very clean. From what I read oil has the tendency to leak down into the connection spot and cause problems.

Camshaft Position Sensor-On top of engine Operation The Engine Management System (EMS) uses the camshaft position sensor to manage sequential fuel injection and as part of misfire diagnosis. The EMS constantly monitors the number of pulses on the signal circuit. The EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses, Diagnostic Trouble Codes (DTCs) should be stored in the EMS. Some engine management systems will then default to multi-port or "gang-fire" injector operation. The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty, most engines will start. However, the EMS misfire diagnostic will likely be affected.
The following symptoms can be caused by an intermittent wiring connections or faulty signal to the EMS.

• Extended crank time with a cold engine
• Intermittent rough running
• Unstable idle
• Bucking
• Hesitation
• Stumble
• Chuggle
• Poor fuel economy
• Stalling on acceleration

A code P0340 could mean one or more of the following has happened:

• a wire or connector in the circuit could be grounded/shorted/broken
• the camshaft position sensor may have failed
• the PCM may have failed
• there exists an open circuit
• the crankshaft position sensor may have failed

With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

• Visually inspect all the wiring and connectors in the circuit
• Check for continuity in the circuit wiring
• Check the operation (voltage) of the camshaft position sensor
• Replace the camshaft position sensor as required
• Check the crankshaft position circuit as well
• Replace circuit wiring and/or connectors as required
• Diagnose/replace the PCM as required

Hope this is for any assistance.

on a neon the cam sensor is located at the drivers side of the engine on the end of the head. it mounts directly over the end of the front camshaft. it is about 3 inches wide and about 2 and a half inches tall. its made of black plastic and has a wire conector in the back of it. these very comonly leak oil so be careful of the o ring and cleaning the mounting surface.

Had the same problem before on my 04 Neon SXT...camshaft sensor is on left side of engine block, take out the battery and to the left of it (face car) is the camshaft position sensor. To change it you'll have to move a few hoses but its plan to see there on the left side of the engine...pretty easy remove and replace. Fixed my problem of car not going above 2k RPM when i replaced the sensor.

buy a new car or try the camshaft position sensor
