Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Had similar problems occur on various Chrysler products manufactured since 1986. What I did was remove the computer from the car and then take a Dremel tool with wire brush attachment and lightly buff all the pins of the computer--tops, sides and backs. After this I then take a jewelers round file and insert the tip into each connector pin hole and very lightly file it to remove any corrision. When I reassembling the connector plug to the computer I placed a good size dab of silicon grease on the plug in the center (acts as a seal when seated). This has eliminated the problem on four different vehicles.

SOURCE: 2004 Dodge SRT-4 keeps coding out

What code number? It could have a wiring short or open to the PCM or to ground. Cam could be out of time, check the timing belt.

SOURCE: 1997 dodge dakota v6 engine wont start replaced

turn the key to the on position a see if you can here a buzzing sound around the fuel tank,if you don't hear a sound then. (be very careful while doing this) with the key off take a fuel line coming from the tank loose,make sure its pointed away from you and turn the key to the on position,see if any gas comes out,if not then your fuel pump is probably bad.

SOURCE: code reads P0340 Camshaft position Sensor circuit

That makes the computor think the timing is off. Replace the sensor and see if that does it. You will then have to have the code cleared (erased) or the light will come back on/stay on.

Check your vacuum lines, it sounds like one did not get reconnected correctly. When this happens you check engine to come on and will cause your engine's rpm's to rise.

I have a po340 a po341 an a po016 code on a 2006 dodge caravan want start


Hi !
P0340 = This indicates that a problem was detected in the camshaft position sensor circuit.
P0341 = Camshaft Position Sensor Circuit Range/Performance
P0016 = Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)

The common point of these errors is the camshaft sensor, so I'm afraid you need to visit a service.

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.

I have 2000 ford focus im working on and I had code po340. so I replaced the cam and crank sensor. It still pops threw the air intake and dies when put in gear. Timming belt is newer and still in time


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

Code PO340


P0340 is a Crankshaft Position Sensor error. It determines firing order and is most likely the cause of your problem. It's mounted near the oil filter on the engine block. Below is a picture of how it appears in your car. Best of luck.

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


Hi,
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
Thanks.

Error code po340 for a 2002 hyundai elantra


Here is what I could find on your P0340 error code:
CausesA 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
Possible SolutionsWith 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
Sounds like since you have replaced both the camshaft and crank shaft sensors you need to look at the PCM.  Go down the line of possible solutions and don't replace the PCM unless nothing else works obviously.  I hope this helps but it looks like you are looking at getting a new PCM.  Good luck.  Thanks for rating my response and for using FixYa!
