How to Match This Part
This aftermarket throttle position sensor (throttle sensor assembly) replaces Yamaha 6C5-85885-00 (catalog form 6C5-85885-00-00). It mounts on the throttle body in the intake assembly and reports throttle opening to the ECU. 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 — 6C5-85885-00 / 6C5-85885-00-00
2. Model code and year — confirm your exact Yamaha F50 / F60 / F70 / F75 / F90 or F115B application against the table below
3. Physical form — round black sensor body with two mounting ears (metal-lined holes) and a side electrical connector (compare with the product images)
The housing face may show marking 7230-16M90 as a secondary identification point. Early Yamaha F115 engines that call for 68V-85885-00 use a different sensor and are not covered by this listing.
- Primary OEM: 6C5-85885-00
- Type: Throttle position sensor
- Fitment: selected Yamaha F50–F90 / F115B
Compatible Engine Models
Confirm your Yamaha model code and year against the table, then verify that the removed sensor or parts fiche calls for 6C5-85885-00 / 6C5-85885-00-00. The identification plate is typically on the port-side transom clamp bracket. Serial location guide: Yamaha Serial Number Guide. Parts diagrams: Yamaha Parts Diagrams.

Installation Guide
- Disconnect the battery and wait for the engine to cool. Follow the Yamaha service procedure before opening the cowling work area.
- Locate the throttle position sensor on the throttle body. Unplug the harness connector and note connector orientation for reassembly.
- Remove the two mounting fasteners, lift the sensor straight off the throttle shaft, and keep any alignment reference from the original position.
- Seat the new sensor on the throttle shaft, start the fasteners, and set the rotational position so the mounting ears align with the throttle body before final tightening.
- 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, O-rings, and sealants are not included with this listing. Use the hardware called for in your service manual.
Troubleshooting & FAQ
Will this fit every Yamaha F115?
No. It is for F115B (6EK / 6EL) applications that call for OEM 6C5-85885-00. Earlier F115A 68V/68W engines use 68V-85885-00 and need a different listing.
What does the 7230-16M90 marking mean?
It is a housing identification marking on the sensor face. Match the Yamaha OEM number 6C5-85885-00 first; use the marking as a secondary visual check against the product images.
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.
