Does anyone know how to fix this. do i need to replace the sensor
I'm getting code 45(Air Temp-short circuit ground) and code 45-(Barometric Pressure Sensor low input.

Thanks for anyhelp that can be provided

 

Yeah...My 04.5 has had the same problem I have repaired mine too...I found what looks like a pretty good solution on ebay under the polaris parts electrical section for 35 bucks. It's an aftermarket wiring harness that lengthens up the harness and has a new wiring with a new connector..It's all water tight. and looks like its pretty good. The item number is 150359590605 I don't know if I want to buy it or wait till mine breaks again. I don't know if this is a one off or if the guy has more of them.

 

Chances are it is not the sensor but the wiring harness. Check the wires going to the the t-bap sensor ( located under your seat infront of your air filter box. ) wires break inside insulation or insulation wears through and wires short to each other or to the chasis. I am on my third wiring harness due to this issue.
