I pulled over at the next stop sign and turned it off and tried to start it. Just cranked but wouldn't turn over. I checked the codes and got the 1684 battery one and a P0340, which translates to "No camshaft Signal being recieved by computer". Is this a sensor issue? Is it better to take to my Mechanic?
I'm going to be putting about 1500 miles on this car in a week starting Saturday and am alittle nervous now. Help Please
this is not necessarily a bad sensor. if you have the tools, I'd try the diag instructions in the FSM first. if you don't have the tools, you could try changing the sensor. moparpartsamerica has the sensor for $40 and its located on the front of the engine on the driver side head. one screw, one connector, and you're done. otherwise it may be a mechanic job...
P0340 OBD-II Trouble Code
Camshaft Position Sensor Circuit Malfunction
What does that mean?
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.
Symptoms can include:
* Hard starting or no start
* Rough running / misfiring
* Loss of engine power
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
