It's a 2005 dodge neon 2005 SXT 2.0, and it can travel for miles at up to 70+ mph, suddenly there is slight tug and it decreases speed and won't get past 2k RPM's for a bit,it tugs along for a bit, then suddenly will allow itself to accelerate. Thanks,I appreciate your

Re: CODE PO 340 SENSOR CIRCUIT CAMSHAFT MALFUNCTION
This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.I hope this helps you

You have an intermittent problem, and it's probably going to be horribly difficult to track down. Your best bet might be to borrow an OBDII scan tool so you can read the codes while the problem is happening.
That mechanic who visually inspected your camshaft position sensor apparently doesn't understand that the sensor can LOOK just FINE while at the same time it's as dead as a doornail. You might try having that one sensor replaced, just to be sure.
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
Camshaft Position Sensor-On top of engine
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. Related Symptoms
code po 340 no camshaft position sensor signal at powertrain control module and code po344 rationality error detected for intermittent loss of camshaft position sensor circuit. hope this will help you!!!!
well actually the camshaft position sensor prob is very easy to fix i just replaced mine on my 2005 it took me a wjole o maybe 50 mins you just need to tak e your battery out and there is a 3x3 in square deal on the side of your engine which is held on by for bolts that take an 8 mm socket its rather easy although the bottom two bolts are kind of a ***** but better then payin someone for such an easy job and not sure bout the knock sensor im doin that one in a couple days when i have a day off from work
