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 thanks

DTC P0340 Camshaft Position (CMP) Sensor Circuit . has single sensor . This is circuit problem , testing the electrical circuit's for the sensor before replacing the sensor should be done . Do you know how to test sensor circuit's ?

How To Diagnose Check Engine Light Code P0340 Cam Position Sensor

Camshaft Position (CMP) Sensor
Right side of the engine, above the timing chain cover, under the power steering pump

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

P0340 is camshaft position sensor #1
before spend any $ inspect the timing belt.
lose timing belt or jump timing will treagar the cod
sensor #1 is right(passenger side)on back of the engine
valve cover.after market sensor wont work long.
buy from dealer once and save headeche.

• egr valve
• egr sensor
• cam shaft sensor
• barometric pressure sensor (map sensor)

vacuum leak somewhere, out of time, broken timing belt or missing teeth.

P0340 code means "Something" is wrong in the timing...
from CMP (Camshaft Position sensor) to the crankshaft bolt.

Very first thing, verify connectors are clean and shiny.
clear all codes, even hard codes.

code p0340 refers to cam shaft position sensora bank 1-circuit malfunction===causes --wiring Cam sensor---ECM. The only connection is the ECM to both units so they may have unpluged the ECM to service the air bag problem. IT could be as simple as using a code reader to reset the CPU. I may also be a coincedence and there may be a fault in the cam position sensor.. I would discuss the matter with the dealer service department to determine what is what.

no need to pump the gas on fuel injected vehicles.
Make sure CPS was installed correctly.

• P0340 - Camshaft position sensor circuit malfunction.
  
• P0457 - Evaporative emission control system leak detected (fuel filler cap loose/off)
  
  There is a bulletin #0398 posted on 05/12/2003 for P0457 - Malfunction indicator lamp (mil) illumination with diagnostic trouble codes p0442, p0455, p0456, p0457, p1442 or check fuel cap lamp illuminated with diagnostic trouble code p0457.

I'd suggest checking with your local dealer, as it may be a fix that is covered by the dealer.

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.

Well either coincidence that the cam sensor went bad, you forgot to plug in the cam sensor, Or you have the cam that the sensor reads off of 1 tooth off. Check to see if its plugged in if yes remove the upper timing cover and see if everything lines up.
