Water Temp Temperature Sensor for Polaris Sportsman 800 EFI 2005-2014

Water Temperature Sensor for Polaris Sportsman 800 EFI

This water temperature sensor for Polaris Sportsman 800 EFI models monitors engine coolant temperature and relays that data to the ECU for proper fuel management and cooling fan activation.

Overview

This water temp sensor for Polaris Sportsman 800 EFI ATVs is a replacement part for the factory coolant temperature sender. The water temperature sensor delivers accurate resistance readings so the engine management system can adjust fueling and trigger the cooling fan as needed. It is intended for riders and mechanics servicing 2005-2014 Sportsman 800 EFI machines.

Specs At A Glance

Good To Know

Q: What happens when the temperature sensor fails? A: The cooling fan may not activate, the gauge may read incorrectly, or a fault code may appear. Fuel delivery can also be affected because the ECU loses coolant temperature data.

Q: Is any special tool needed for installation? A: A basic socket set and a drain pan for coolant are usually all that is required. Apply thread sealant if specified and refill coolant afterward.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
