Hello All,

First post here looking for some assitance. I have a 2012 Ranger xp800 and recently it begain to throw up the check engine light whenever I was throttling up or powering through some terrain. If I let off the gas, eventually the check engine light would go out. Seems to run fine otherwise. I checked the Code and it shows a 0-3598-4 code which translates (from what I have been able to research) the following "ECU Output Supply Voltage 2 - Voltage too low". I am no mechanic nor do I profess to being even slightly handy when it comes to motors and such, so I am trying to find out what exactly that means... What is ECU output supply voltage 2, and what would cause it to be too low?

Any help would be appreciated.

Thanks

Welcome to PRC.

My first guess would be a bad voltage regulator....not all that uncommon on the 800's. Next time it shows that, check your voltage. If the problem is intermittent, it could just be a bad connection.

Thanks for the welcome. The problem does not seem to be intermittent, the check engine light comes on when I throttle up or I am powering through mud or requiring more than normal power. It will stay lit until I let off the gas and the engine throttles down. I have been looking into this and people have been saying it could be my ECU or my TPS sensor that are stuck or blocked, or broken. I will explore the voltage regulator as well to see if that is part of the problem.

Thanks

......people have been saying it could be my ECU or my TPS sensor that are stuck or blocked, or broken......

ECU issues are very rare, but "possible". Broken wires to the TPS are not uncommon, but typically cause it to run pretty rough and you mentioned that it is running fine. Checking the voltage is pretty simple and would be the first thing I would rule out. Also check to make sure all of your relays and fuses are seated well and free of corrosion.
