    Code P 0344 Cam Sensor

    I got code P 0344 and swapped cam sensors with my other ski. Other ski ran fine with the sensor from the bad ski, but no change on the ski with issues after swapping. Both have 2004-05 engines/electronics. What else could it be? Also got P 0500, but it doesn't exist in the code list to my knowledge.

    As you will note from my low post count that I am not an expert and do not claim to be, so this is just my story.

    Bearing and ceramics bite it on my 2006 GTX Ltd. Shop replaced and pulled engine and cleaned it up. 2 hrs after fix the Cam Chain breaks and shut down the ski with the P 0344 code. Under Warranty my shop got BRP to replace with a NEW long block.

    Hope your outcome is better, and based on following your post for the last three years I doubt these stories are related.

    No supercharger issues for this engine. Cam and engine timing were checked 3 times. The ski struggles to start, and when it does (rarely) it will idle at about 1200 RPM and then shut off.

    I'm still searching for diagnostic advice on this. Would incorrect engine timing cause the cam code and poor running symptoms? Or conversely, could a fault in the cam sensor circuit cause poor running symptoms? Compression is at 65-80 PSI for all cylinders. Engine timing has been triple checked by the book. Head was just re-done with all new valves. Any help is greatly appreciated.

    Going through the exact same thing right now(P0344) but mine runs fine on the hose(just starts a little hard).....SC is fine.

    It's at a dealer now(still under warrantee),they said it's the sensor,they're (supposedly)replacing it tomorrow,will post the outcome.

    Have the plugs for the tops valve and front oil pressure switch been mixed up? Also check the top left 10amp fuse in the mpem. Then check for 12 volts at the yellow/orange wire on the cam sensor plug.

    There is no P0500 in the BUDS system as a code, but judging by the close P05xx codes, the way I would start is to clean out the throttle IAC gallery, and its galley-way.

    Sounds like the IAC cannot pick-up the idle for the engine fast enough to me, and when cold it will choke itself, rather than raise the idle to take this into account.

    The cylinder pressure is a little suspect to me if it varies by the numbers you give also.

    My $0.02.
