There might be a possibility that you disrupted the position on the speed sensor magnet pickup , the rubber sensor cap may have dislodged from the chain case cover upon reassembly....Went into the chain case to change gears and upon re-assembly, forgot to plug in speed sensor. Sled threw code P1009. I stopped and plugged the speed sensor back in, but code still flashed and speedo won't work. Disconnected battery and still have coolant code. Hooked up my flasher and read the code, but can't clear it
In addition, the odometer adds miles exponentially. Traveling 2 miles will put 30 on the odometer.
Anyone ever had experience this?
