    code 15 is engine temp sensor the sensor that screws to the number 1 cylinder, Make sure it's plugged in correctly.

    Also check the engine when riding to see if its hot or not when the code sounds because ive had sensor go bad before and check the strainer and pisser lines too for blockage.
