Water Temp Temperature Sensor for Polaris RZR S 800 EFI 2009-2014

Water Temperature Sensor for Polaris RZR S 800 EFI

This water temperature sensor monitors coolant temperature on the Polaris RZR S 800 EFI, delivering accurate readings to the gauge and engine management system.

Overview

This water temperature sensor is a direct-fit replacement for the Polaris RZR S 800 EFI, built to track coolant temperature and relay that data to the ECU and dash gauge. It suits riders and mechanics servicing 2009 through 2014 models who need a reliable temperature sensor at a sensible price. When temperature readings turn erratic or fail completely, this sensor gets the system reading correctly again.

Specs At A Glance

Good To Know

Q: How do I know if my temperature sensor has failed? A: A faulty sensor often causes an erratic or dead temperature gauge, poor running conditions, or a check engine light. Replacing it restores accurate readings to the gauge and ECU.

Q: Is this sensor a plug-and-play replacement? A: Yes, it installs in the factory coolant port and connects to the original wiring harness without modification. Always confirm your model year and connector style before ordering.

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