Tht is a camshaft sensor code. you probablyhave a sensor just starting to go bad and when it does the truck won't start no more. if you want to look atthe wire haness going to the cam sensor and if it looks good thaan swap the cam sensor.

also if you give the size engine you have i can give you a test to do with a meter to check it. but most of the time if thevehicle is running you can't tell. it has to be broke to tet it. but to re assure you i istall alot of cam sensor nd also crank sensor. so it is a very common problem...goodluckand ask any more question you have.

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.

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.

Po340 and po344 intrepid


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!
