Overview

The Yamaha 8FP-85886-00-00 Air Temperature Sensor is a genuine OEM replacement part designed to restore factory-correct air temperature monitoring to your Yamaha vehicle's engine management system. The sensor measures the temperature of ambient air entering the intake, providing real-time data to the engine control unit so it can continuously optimize the air-fuel ratio. This is critical for maintaining smooth throttle response, consistent power delivery, and efficient fuel consumption across a wide range of operating temperatures and riding conditions.

What makes this sensor notable is its exceptionally broad compatibility within the 2018 Yamaha lineup. It services sport bikes like the YZF-R1 and YZF-R6, motocross and off-road machines including the YZ250F and YZ450FX, sport ATVs like the YFZ450R, utility ATVs such as the Kodiak 700 EPS and Grizzly EPS, and side-by-sides including the YXZ1000R EPS, Viking, and Wolverine families. As a genuine Yamaha part, it plugs directly into the factory wiring harness and sensor mount with no modifications required, ensuring the same reliable performance and longevity as the original component it replaces.
