    I have the exact same problem with my 95 neon. I also replaced the camshaft sensor, the fuel pump, and some other sensor that can't remember the name of. All with no luck. My next adventure is to tear apart all the wiring in the car for a bad connection or ground. wondering if you have solved the problem and could shorten my efforts.

Code PO340 bad camshaft sensor. I replaced the sensor and i the car still wont start. I still get the same code and the car will not start.

Trevor: Alittle known fact is that most Chrysler cars do not need a full OBD code reader! By performing the "Key-Dance" you can show the codes on the odometer without any reader! Look for info on how to read the codes with the ignition key.

On your problem, you need to check the wiring and connectors, and also check the proper cams and belt timing, as it is difficult but sometimes an out of timing (one tooth only) misalignment can make the car not to start.

Dosen't start cranck ok i change comp on dash sais

One thing to check: the Neon SOHC engines have a design flaw where the pin that aligns the timing belt sprocket to the camshaft shears off. The sprocket can then slip but still appears to be lined up properly. On later models the engine control software detects this because the crankshaft and camshaft sensors are out of sync and the result is that it can shut down the ignition and fuel injection but not set a code (not enough run time). Verify by taking out plugs and checking compression. If the camshaft is out of time, compression will be low. Also, valves can be bent if the sprocket slipped too much. This is the problem I had.

Po340 code on my 99 neon. I have no clue what a crankshaft sensor is or this an expensive fix? it has 135000miles on it.

Crankshaft sensors tell the computer which cylinder is on top dead center so the computer knows which cylinder gets the spark and the fuel when working with the camshaft sensor as well. Neon crank sensors are on the back side of the engine or firewall side. Due to a lack of moving air over the sensor, the wiring can become brittle and break. The sensors have also been upgraded to a new connector and pigtail wiring end. Expensive? can be if a new sensor and wiring is needed. Recommend taking it to a shop to get you going again.

Car cuts out whiles driving and does not start for a while

im pretty sure if you have someone check the engine computer for fault codes youll find either a po335,po725 or po340.these relate to failures with your crankshaft and camshaft position sensors.relatively inexpensive fix at the outset 250.00 to replace both.i would recommend replacing both as they are identical sensors and acommon source of trouble on these models.

Check engine light bmw 325i code 340

Code PO340 "Camshaft Position Sensor Circuit Malfunction". Now that does not mean that if you simply replace the sensor your problem will be solved. It can be simply loose, cut, or corroded wiring. It can also be something entirely different. This is where diagnostic skills come in.

My 2000 plymouth neon cuts off on me after i

If your check engine light is coming on, then there should be a trouble code stored in your computer to tell you what area to look in for problem. Run into an autozone, or Pep Boys & get a free scan and see what they say comes up for codes & then if not obvious what the problem is, get back to us & we'll help you out.

For what sensor is the code po340 on a dodge neon 04 and how i change.

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.

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
