While Yamaha has been praised for starting the UTV craze with the Rhino 660 they did make a few mistakes. One of these that we encounter on a regular basis is the reverse sensor below the airbox. Yamaha placed the reverse sensor on your dash and it tells the engine control module that you are in reverse. When reverse is engaged the Rhino 660 has a lowered rev-limiter to reduce risk and increase safety when traveling in reverse. Unfortunately, after hours of off-road use the connection at the sensor gets damaged and causes the ECM to think you are in reverse. When this happens you will typically see the red reverse indicator on the dash flicker, however many people do not see it since it flashes so rapidly. When this happens the Rhino will literally fall on its face and sputter. Thankfully, the fix to this problem is fairly simple. You will need to remove your center cowl and then remove the airbox. Beneath the airbox you will find a single pin straight style connector. The opening on this plug gets enlarged and allows the plug to wiggle on the sensor creating a false reverse. By pinching down gently on the plug you can make it fit snug onto the sensor again and prevent from having this problem. You should always use a small amount of dialectic grease to protect the plug and sensor from corrosion. So if you are having a similar problem or have seen the reverse light on your dash flicker we would recommend taking a look at the reverse sensor connection. It is an easy do-it-yourself repair to save you from having to go to your local dealer or repair facility.
