3P6-85885-00-00 Throttle Position Sensor Fit for Yamaha WR25R FJR1300 WR250R X

Throttle Position Sensor for Yamaha

This Throttle Position Sensor 3P6-85885-00-00 is an electronic component that monitors throttle angle and sends the signal to the ECU for optimized fuel delivery on Yamaha motorcycles.

Overview

This Throttle Position Sensor 3P6-85885-00-00 is a variable resistor type sensor that measures throttle plate position and relays that data to the engine control unit. It is designed for Yamaha WR250R, WR25R, and FJR1300 models to ensure accurate air-fuel mixture and responsive acceleration.

Built For Performance

• Interchangeable with OEM part number 3P6-85885-00-00
• Durable plastic housing protects internal circuitry
• Precision wiper track for linear output signal
• Sealed connections prevent dirt and moisture ingress
• Factory-matched resistance range for accurate ECU readings

Fits These Machines

• for Yamaha WR250R
• for Yamaha WR25R
• for Yamaha FJR1300

On-The-Job Use

• Mounts directly onto the throttle body to track throttle position
• Used during engine startup and idle to set proper fuel mixture
• Critical for smooth throttle response during acceleration
• Common replacement when engine hesitation or rough idle occurs

Specs At A Glance

Good To Know

Q: What are signs that this sensor needs replacement?
A: Symptoms include stalling, poor acceleration, or a check engine light related to throttle position circuit faults.

Q: Can I test this sensor before installing?
A: Yes, use a multimeter to check the resistance sweep across the terminals as you rotate the throttle shaft; it should change smoothly without dead spots.

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