This speed sensor is an electronic component that monitors the rotational speed of the vehicle's transmission output shaft or wheel hub. It generates an electrical signal proportional to speed, which is crucial for the engine control module (ECM) to manage functions like cruise control, ABS, and transmission shifting. A faulty sensor will not provide accurate speed data, leading to erratic performance and dashboard warnings, unlike a functioning sensor that ensures precise system control. Observable symptoms include the speedometer not working, ABS warning lights illuminating, or the transmission shifting improperly.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The most immediate symptom is often a non-functional speedometer or odometer. Additionally, the ABS warning light may illuminate on the dashboard, and the transmission may exhibit erratic shifting patterns or fail to engage cruise control. Ignoring these symptoms can lead to incorrect gear selection, reduced fuel efficiency, and potential safety system failures.
Carefully clean the sensor mounting bore to ensure a proper seal and accurate reading, and avoid using excessive force when threading the sensor into place. Ensure the electrical connector clicks securely into place.
Inspect the wiring harness and connector for any signs of damage or corrosion when replacing the speed sensor.
