This tachograph speed sensor accurately measures the rotational speed of the vehicle's drivetrain, converting it into an electrical signal for the tachograph and speedometer. It is crucial for recording driving time, speed, and distance, ensuring compliance with regulations and providing essential operational data. A worn or faulty sensor may produce intermittent or incorrect speed readings, or cease to function altogether. Operators might notice the speedometer or tachograph displaying erratic values, or failing to register any data.
Always verify with serial number before ordering.

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.
The first indication of a faulty speed sensor is often an erratic or non-functional speedometer and tachograph. If the issue persists, it can lead to incorrect logging of driving data, potentially resulting in regulatory non-compliance. In severe cases, it may affect other vehicle systems that rely on speed input.
Ensure the vehicle is safely supported and the transmission is in neutral before removing the old sensor. Do not use excessive force when threading the new sensor into the transmission housing.
Check the condition of the transmission output shaft and any associated drive gears for wear or damage when replacing the speed sensor.
