This throttle position sensor (TPS) accurately measures the throttle pedal's position and sends this data to the engine control unit (ECU) for precise fuel and air management. It is constructed with high-grade materials to ensure consistent and reliable readings, unlike a worn sensor that provides erratic data. Observable symptoms of a faulty TPS include rough idling, hesitation during acceleration, poor fuel economy, or the engine entering a limp-home mode.

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.
A failing throttle position sensor may initially cause slight hesitation when the accelerator pedal is pressed. If the issue progresses, the engine may run roughly, experience significant power loss, or trigger a check engine light with related fault codes. Continued operation with a faulty sensor can lead to increased fuel consumption and potential engine damage.
Before removing the old sensor, mark its exact position on the throttle shaft to aid in aligning the new one. Ensure the new sensor is properly seated and secured to prevent air leaks into the intake manifold.
Inspect the throttle linkage and return spring for proper operation and wear when replacing the throttle position sensor.
