RS150-TPS Motorcycle Throttle Valve Sensor for RS150 and RS150R EFI Systems

This throttle valve sensor, designated RS150-TPS, serves as a direct replacement component for motorcycles with electronic fuel injection (EFI). It is specifically compatible with RS150 and RS150R model motorcycles, providing the correct part to monitor throttle plate position. The sensor's output is critical for the engine control unit (ECU) to calculate appropriate fuel delivery based on rider throttle input. Supplied as a single unit, it is ready for installation to address sensor failure or as part of routine system maintenance, ensuring the EFI system receives accurate throttle position data.

Features and Construction

The product is defined by its model number and application range. Its primary role is to replace the original throttle position sensor on compatible motorcycles.

Model Specification and Compatibility

The sensor is listed under the specification RS150-TPS. This model number indicates its design for use with RS150 series motorcycles. Confirmed compatible vehicle models include the RS150 and the RS150R variant. This clear compatibility information helps ensure the part is suitable for the electrical connectors and mounting provisions on these specific bikes.

Function and System Integration

As a throttle valve sensor (TPS), its function is to measure the angle of the throttle valve (butterfly) inside the throttle body. This measurement is sent as a variable voltage signal to the motorcycle's ECU. The ECU uses this data, along with inputs from other sensors, to determine the correct air/fuel mixture for efficient engine operation under all riding conditions, from idle to full throttle.

Uses and Placement

The sensor is a dedicated component for motorcycle fuel systems, fitting into specific maintenance and repair contexts.

Repair and Maintenance Use

The primary use case is as a replacement part for the original equipment throttle position sensor on RS150 or RS150R motorcycles. This may be necessary if the original sensor exhibits faults such as erratic idle, poor throttle response, or triggers an engine fault code related to throttle position. It provides a direct substitute to restore the EFI system's sensing capability.

Direct Installation

As a direct replacement unit, it is designed to fit into the existing throttle body assembly on the compatible motorcycles. Installation typically involves disconnecting the electrical connector, removing the mounting screws of the old sensor, fitting the new sensor, and reconnecting the wiring. Proper installation is followed by any necessary ECU recalibration or idle relearn procedure as specified by the vehicle manufacturer.

Benefits and Buying Value

The value of this component lies in its defined specification and application, offering a targeted solution for owners and mechanics.

Defined Compatibility

The clear identification as RS150-TPS and listing of compatible models (RS150, RS150R) reduces the risk of ordering an incorrect part. This specificity provides confidence that the sensor will match the required electrical characteristics and physical fitment of the original component.

Why Choose This Product

For owners or technicians working on RS150 or RS150R motorcycles needing a throttle position sensor, this product offers a directly applicable part. Its value is in providing the specified component needed to address a sensor-related running issue or to complete a repair job with a part that matches the bike's requirements.
