Throttle Position Sensor for KTM 250/350/450 SX-F, 125/250/300 SX
This throttle position sensor (TPS) monitors throttle plate angle and sends that signal to the ECU so the engine receives the correct fuel and ignition timing for KTM models.
Overview
This throttle position sensor measures throttle valve position and converts it into an electrical signal for the engine control unit, ensuring precise fuel delivery and ignition timing. It is a direct replacement for the original sensor on KTM off-road motorcycles, restoring smooth throttle response and consistent idle. The sensor is built to withstand the harsh vibrations and temperature extremes of off-road riding.

Good To Know
Q: How do I know if this sensor fits my specific model year? A: Match your bike's VIN or engine serial number against the OEM part number 79041077044, as model year changes can affect the connector style.
Q: What symptoms indicate a failing throttle position sensor? A: Common signs are erratic idle, hesitation on throttle opening, or a check engine light with a TPS-related fault code.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
