    Fault Code P0340 & P0231

    I am getting the P0340 & P0231 on my 2010 RxtX. I pulled all my fuses and checked along with battery. Voltage is reading 13.07 to 13.00. and hasn't dropped below 12.85 while turning it over. Ran it a couple days ago for an hour with no problems or codes. Any idea's and does anyone have a list of fault codes for this model? I know there are generic Sea-Doo lists. Thanks

    P0340 = ECM Camshaft 1 signal error
    P0231 = ECM Fuel pump open circuit or short to ground

    Dude, you're racing and you don't have a manual?

    1) Are you running a stock ecu?
    2) Have you checked all of your electrical connections, specifically the CAN connection by the battery? I would basically guarentee something is loose and causing you to code out (unless you are running a reflash)

    ECU has been redone by Bo @ Neptune Racing. All of the fuses in both black boxes are good with no water and plenty of grease with no corrosion. I will flip them over and make sure done have come out the back of them. Thanks for the help and will see what I can do. Something must of come lose because it ran fine the other day and now nothing. Damn Gremlins!

    Jawz, plan on calling you later tonight when I start driving home if that works. Once again you might be able to save the day...what a great guy, and good racer.

    Does anyone have the manual in a compressed form for email or able to send a CD-ROM of one? Only one I have to trade is for 2004 Honda R12X, bout 380 pages.
