This Throttle Position Sensor is a critical component in the engine's electronic control system, measuring the throttle pedal's position to inform the engine control unit (ECU) about driver input. It ensures accurate fuel delivery and engine response by providing a precise electrical signal, unlike a worn sensor which can drift or fail, leading to erratic performance. Operators may notice symptoms such as poor acceleration, inconsistent engine speed, or the check engine light illuminating when this sensor begins to fail.

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial signs of a failing throttle position sensor may include hesitant acceleration or a noticeable drop in engine power. If left unaddressed, the engine may begin to run rough, stall intermittently, or fail to start. Continued operation with a faulty sensor can lead to increased fuel consumption and potential damage to other engine components due to improper fueling.
Ensure the throttle body is clean before installation, as debris can interfere with the sensor's operation. Avoid over-tightening the mounting screws, as this can damage the sensor housing or strip the threads.
Inspect the throttle body and linkage for any signs of wear or damage when replacing the throttle position sensor.
