Most likely yes. It's not that the cam is out of position (that's controlled by the timing belt, so as long as the belt hasn't slipped, the cam is where it should be). What's more likely is that the cam sensor has gone bad, as you're suggesting, and it's not able to tell the computer the position of the cam, or it's telling the computer that the cam is in a position that the computer knows it can't be.

Replace the cam sensor and you'll be fine.

    I have a nissan murano 2005 with the code p1701 and a p0340 how can i use them to repair these codes


    Nissan Murano P0340 2005 Nissan Murano - Camshaft Position Sensor Circuit
    Possible causes- Faulty Camshaft Position Sensor-
    Camshaft Position Sensor harness is open or shorted- Camshaft Position Sensor circuit poor electrical connection- Faulty starter motor- Starting system circuit-
    Dead (Weak) battery
    P1701- Fuel trim

    I would suggest replacing the camshaft position sensor. When the sensor fails it can cause changes in fuel system that the computer can detect. So I suspect once the camshaft sensor ivreplaced that the P1701 code will be gone.

    Car died ,code 340 & battery went dead too


    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

    Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

    Thank you for using FixYa, have a nice day.

    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.

    Diagnostic code P 340 and P 341 Camshaft Position Sensor Malfunction for a Dodge Ram Diesel 2500. What does it mean?


    The Camshaft Position Sensor tells the PCM (computer) the position of the Camshaft Position. This Sensor sychronized along with several other Sensors including the Crankshaft Position Sensor the firing of the electronics to the spark plugs of each cylinder.
    It is not difficult to replace and relatively inexpensive.
    1. Disconnect the Negative side of the Battery,
    2. Locate the Sensor and unplug.
    3. Remove the Position Sensor retaining bolt.
    4. Pull out the Sensor.
    Replacement is reverse of above order.
    Hint: use fresh engine oil on the end/sides of the Sensor especially around the rubber o-ring(s) to ease pushing the Sensor into proper position.
