Product Function

The Throttle Position Sensor (TPS) detects the position of the throttle and sends this information to the ECU / engine management system.

This information is used to correctly control engine operation according to throttle demand.

A faulty TPS may contribute to symptoms such as:

Poor throttle response
Irregular or unstable running
Incorrect idle
Hesitation during acceleration
Engine warning / fault indication
Reduced engine performance

These symptoms can also be caused by other fuel, air, ignition, wiring or sensor faults, so correct diagnosis is recommended before replacing the sensor.

⚠️ Important Compatibility Warning

This sensor does NOT fit every Yamaha 115 HP outboard.

It is for selected F115 / LF115 4-stroke engine families using Yamaha 68V-85885-00.

Before ordering, please check:

Engine model
Engine family / prefix
Model year
Complete serial number
Original sensor part number
Electrical connector

The safest compatibility check is that your engine specifies:

68V-85885-00 / 68V-85885-00-00

If the part looks the same as yours, this does not always mean it is the correct part for your outboard.

If unsure, send SSI Marine your engine model + horsepower + complete serial number and we will help check compatibility.

Buyer Responsibility

It is the buyer's responsibility to confirm compatibility before purchasing.

OEM part numbers are used for identification and reference purposes only.

Correct diagnosis is recommended before replacing a throttle position sensor, as similar symptoms can be caused by throttle-body adjustment, wiring, ECU, fuel-system or other sensor faults.
