View Full Version : Yamaha F150 speed sensor question

07-29-2013, 03:06 PM
I have a 2006 F150 Yamaha with the digital gauge pkg. The speed seems to have gone haywire. Sometimes it stays at zero and other times it will slowly go up to speed over 10 to 15 minutes. Then it might stay a WOT speed even after you stop. The question is where is the sensor that pickups the speed? The old pkg used a external pickup but I can not fond any such thing now. Is it somehow been integrated into the lower unit of the motor now? Any help would be greatly appreciated.
