Review on 🌡️ Rider Air Temp Sensor for Polaris RANGER 4X4 500 EFI 700 EFI 800 EFI, SCRAMBLER 850 1000, SPORTSMAN/SPORTSMAN TOURING 1000 500EFI 850 Forest Tractor 500 - Upgraded Replacement 2410687 by Brian Stepp

This solved the shutdown problem for me. The machine turned off rather randomly when it was hot. Normally there was no heat warning on the machine. I pulled out the codes and one of them pointed to an air temperature sensor. This part is easy to get and cheap to replace. You can test yours by removing it and connecting it to an ohmmeter (multimeter) at room temperature. The manual says it should be around 2.45. My bad one was around 1.5 and the new one around 2.25 (it varies a bit with room temperature).
