Getting code 45 (Barometric Pressure Sensor: Circuit Low Input) on my 09 sportsman 500x2 what does it mean?
How did you know what wire from the new harness matched existing wiring? How did you match the wires?This forum helped me a lot recently and I wanted to add something to this that I discovered. So I was getting the check engine light with the same codes. I started looking to replace the sensor but instead checked the wiring harness after reading this forum. As you can see in the cut off wiring harness the wires are showing through the rubber insulation and it finally gave out. I believe this was caused by the sharp aluminum wrap that was rubbing up against it in the other picture. I bought a Xislet 4 pin T-Bap Temp/Baro sensor wire replacement harness for polaris ranger and sportsman 700 750 and 800 EFI's from Amazon. I cut the end off the old one and replaced it with the new one giving it a lot of extra length. It worked and the codes went away and the check engine light went off. $35 repair and I didn't have to take it to a shop.
