You will get a cam shaft code if the timing belt is broken. This could be you issue. I would check the timing belt before you go any further.
It can damage your engine if you keep trying to start it.

SOURCE: code p0340 replaced sensor still won't start

I fixed this issue before with more than just a cam position sensor.
I had to replace the crank sensor and clean all the engine wiring grounding points.

My 2002 infiniti q45 turned off while sitting at a traffic light. Tried to start itbut in won't start. Diagnosed it and It showed cam shaft position sensor circuit malfunction. .code P0340...I replaced...


Did you check your fuel filter? Did you have a shop install the sensors? If they are not positioned in correctly, it won't work. Have you had your fuel pump checked as well? That's in your fuel tank. With this high end car, there may be a reset code as well.

I have 2 engine codes on my 2005 dodge neon. they are p0325 and p0340. the car has problem starting and misses badly for a while. What is the problem and how do i fix it? thanx for the help!


the p0325 code pertains to a knock censor. the p0340 is for your cam shaft sensor. i've had this problem before. try replacing the cam shaft censor first and run the codes again to see if the other still comes up. it should fix the problem. hope this helps

Getting code P0340 (no cam shaft signal being received by the computer). Is there an esy fix for this - for instance, resettingthe computer?


it's pretty easy to replace the cam sensor, and to check the harness to make sure that the wiring to the computer is ok. most often it is the sensor. (I worked for Chrysler for ten years). you could try resetting the computer, but if it's a hard code and the car won't start, replace the sensor.

04 dodge neon showing P0325 and P0340 codes at same time.


Code 0325 is for a Knock sensor. Code 0340 is for the Cam sensor #1 if this is an engine with 2 heads and it is an indication of a single sensor on single head engines.

So if you do have a multiple hed engine, you may have removed the good sensor and left the bad sensor in the other head.

Remember to wipe the computer memory after installing new parts.

2005 hyndia accent check engine light came on,1 day later car stalled and would not start. code p0340 cam shaft sensor replaced it still wont start gets spark fuel pump turns on any thoughts or suggestions...


Check that the timing has not jumped, incorrect timing will trigger a cam sensor code as the ecu can not work out the correct position of the cam.

I have a diagnostic code 340 and 320 on a 1997 Jeep Cherokee. What might the problem be?


DTC P0340 - Camshaft Position Sensor Circuit Malfunction
Symptoms can include:
  • Hard starting or no start
  • Rough running / misfiring
  • Loss of engine power
Causes: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

Possible Solutions: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

DTC P0320 also have with this wrong.

Code p0340 on 2000 dodge intrepid


it might be the cam shaft sensor it might be the crank shaft sensor the best thing to do is replace them bolth. but it does sound like it may be either one because if one goes out the other will still work but when starting the car it will take longer for it to read from either or the one sensor that is still working because they work together to tell the system to deliver the gas. im pretty positive that it is either the cam or crank shaft sensor

I have a 98 Fordwindstar 3.8 . It failed emission on code P0340 . I replaced the cam shaft position sensor it still shows code P0340 what else could it be?


the input to the sensor must also be checked. this link provides some diagnostic procedures. diagnosis for camshaft and crankshaft sensors are similar, as stated in the article.

Car would not start, after siiting for an hour it did start .


mcdevito75 here, BEST BET, let the shop do this work, too many un forseen problems could come up. The stalling and unable to start for a while could also be a bad ignition module, no test for this part, but I would have it changed, for if it is a bad ignition module, all this other work will not fix the stalling and later start of your car.
