This throttle position sensor accurately measures the throttle pedal's position and transmits this data to the engine control unit (ECU) for precise fuel and air management. It is constructed from durable materials to withstand engine bay temperatures and vibrations, ensuring reliable performance compared to a worn sensor that may provide erratic readings. Operators may notice a lack of engine power, rough idling, or the check engine light illuminating when this sensor begins to fail.

Installation & Application Notes

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.

Failure Symptoms

An illuminated check engine light is often the first sign of a failing throttle position sensor. The engine may then exhibit poor acceleration, rough idling, and inconsistent power delivery. Continued operation with a faulty sensor can lead to increased fuel consumption and potential drivability issues.

Installation Tip

Ensure the new sensor is properly aligned with the throttle linkage before securing it to prevent binding. Do not force the sensor into place, as this can damage the internal components or the throttle body.

Service Note

Inspect the throttle body for carbon buildup and clean if necessary when replacing the throttle position sensor.
