Take a look at this link http://www.obd-codes.com/p0340.  The problem lies in the cam shaft sensor circuit which means that it isn't necessarily the sensor itself.  Read what that page has to say and just start from the top and work your way down the solutions.  As far as how much it cost, it obviously depends on what is wrong, but assuming it is your cam shaft sensor you can buy the part for around forty dollars at AutoZone.  Let me know if you have any other questions.  Thanks for rating my response and for using FixYa!

PO340 IS NO CAMSHAFT POSITION SENSOR CIRCUIT FAILURE.YOUR CAR IS GOING TO HAVE BE REPROGRAMMED BEFORE PCM WILL RECOGNIZE THE NEW CAMSHAFT SENSOR.

SOURCE: 2003 Hyundai Sonata starts when cold and dies after warming up.

Wiring problem or the ECU (engine control unit) is defective. Try this, disconnect the battery cables from the battery and short/touch them together for 30 seconds (do not do this if connected to the battery). Then, reconnect the cables to the battery posts & see if that fixes it. If it doesn't, then there is a wiring problem associated with the cam pos snsr or the ECU has gone bad.

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

P0340 - Cam Timing

SYMPTOMS/CONDITIONS
of a mistimed camshaft system (all must apply):
  1. Camshafts have previously been removed from the engine.
  2. Engine runs rough.
  3. Vehicle sets P0340 (camshaft sensor code).
  4. Camshaft sensor has been checked with a known, properly operating camshaft sensor.

CORRECT:
The diagram in the manuals should show the timing marks on both cam gears to be on the blue timing chain links.

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.

DTC - PO340, PO325


My Nissan micro 2004 model just stopped in the middle of the road one day then the engine management light came on, anyway took it to my local garage TWK Thomas who said it was a cam shaft sensor problem. OK so sensor was put on, engine management light went off for two days only. So went back to the garage they said that another sensor should be fitted on the opposite side. And then the problem should be rectified, but i had given the £160 for this problem to be fixed the first time. I decided it was time to take it to another garage Nis Tec they put it on the computer and a code po340 came up would this mean another sensor or the cam chain has stretched please help. ...claire

I have a 2000 chrysler concorde that the engine light just popped on - the error codes are po302, po420, po340


P0302-cylinder #2 misfire detected
P0420- catalyst efficiency below threshold bank 1
P0340-No cam signal at PCM.
The Cam sensor most likely needs to be replaced first. Clear the codes after that and drive and see what comes back on.
