Hi, I have a 1992 1660 and I have been having some issues lately with the readout for the ground speed and engine rpm. If I'm sitting still with the engine running it says that I have an engine rpm of 2610, which I don't. It also says that my speed is 29.1 mph, which it isn't. The strange thing is that when I move, the speed resets to normal and the screen switches automatically to engine rpm and reads 000. If I stop moving the speed reads 29.1 and the engine rpm reads 2610. Rotor speed and fan speed are working. I've checked the engine speed sensor connection as well as the sensor on the transmission and those are clean and good. Do I have a bad sensor? I was wondering if anyone here has any ideas. Thanks for any replies!
