Throttle Position Sensor 6S1-85885-01 – Fits Yamaha F150/F200/F225

How to Match This Part

This aftermarket throttle position sensor (throttle sensor assembly) replaces Yamaha 6S1-85885-01 (catalog form 6S1-85885-01-00). It also supersedes the earlier Yamaha number 6S1-85885-00 / 6S1-85885-00-00. The sensor mounts on the throttle body / intake assembly and reports throttle opening to the ECU for fuel and ignition control. This unit is new production, not a remanufactured or rebuilt sensor.

Match this part in this order:
1. OEM number on the removed sensor or in your parts catalog — 6S1-85885-01 / 6S1-85885-01-00 (or superseded 6S1-85885-00 / 6S1-85885-00-00)
2. Model code and year — Yamaha F150 / FL150 / LF150 (2005–2024), or F200 / FL200 / LF200 and F225 / FL225 / LF225 (2006–2011) four-stroke applications that call for this OEM
3. Physical form — flange-mount sensor body with an integral electrical connector for the throttle-body / intake location (compare with the product images)

This listing is not for Yamaha F115 / FL115 sensors that use OEM 68V-85885-00, and it is not a catch-all for every 150–225 HP Yamaha. If the number on your removed part does not match 6S1-85885-01 / 6S1-85885-00 (or the -00 catalog suffixes), do not use this listing.

• Primary OEM: 6S1-85885-01
• Type: Throttle position sensor
• Fitment: Yamaha F150 / F200 / F225 families

Compatible Engine Models

Confirm your Yamaha model code and year against the table below, then verify that the removed sensor is marked 6S1-85885-01 / 6S1-85885-01-00 or the superseded 6S1-85885-00 / 6S1-85885-00-00. The serial number plate is typically on the port-side transom clamp bracket. Serial location guide: Yamaha Serial Number Guide. Parts diagrams: Yamaha Parts Diagrams.

Technical Specifications

Installation Guide

1. Disconnect the battery and wait for the engine to cool. Relieve residual fuel-system pressure per the Yamaha service procedure before opening the cowling work area.
2. Locate the throttle position sensor on the throttle body / intake assembly. Unplug the harness connector and note connector orientation for reassembly.
3. Remove the mounting fasteners, lift the sensor straight off the throttle shaft, and keep any alignment reference from the original position.
4. Seat the new sensor on the throttle shaft, start the fasteners, and set the rotational position so the sensor aligns with the mount before final tightening.
5. Reconnect the harness until it locks. Reconnect the battery, then verify idle quality and throttle response. Perform any Yamaha-specified TPS base-position check or idle adaptation after replacement.

Mounting screws, gaskets, and sealants are not included with this listing. Use the hardware called for in your service manual.

Troubleshooting & FAQ

Will this fit every Yamaha 150–225 HP 4-stroke?
No. It is only for engines that call for OEM 6S1-85885-01 / 6S1-85885-00 (catalog -00 suffixes). Verified coverage here is F150 / FL150 / LF150 (2005–2024) and selected F200 / F225 families (2006–2011). Later or other-generation engines that use a different OEM sensor number need a different listing.

Is this the same as the F115 sensor 68V-85885-00?
No. 68V-85885-00 is a different Yamaha TPS application (F115 / FL115). Do not interchange the two.

Is this a remanufactured sensor?
No. This is a new aftermarket unit.

What symptoms point to a failing TPS?
Unstable idle, hesitation on acceleration, or throttle-related fault codes can involve the TPS. Confirm the OEM number and diagnose connectors and wiring before replacing the sensor alone.
