Dongfeng Truck Spare Parts Electric Odometer Sensor C03054-20

The C03054-20 Electronic Vehicle Speed and Odometer Sensor Assembly is a precision-engineered sensor module designed for accurate measurement and transmission of vehicle speed and distance data in commercial trucks and heavy-duty vehicles. This sensor integrates with the vehicle’s transmission output shaft or differential housing to detect rotational movement via magnetic or Hall-effect sensing technology, converting mechanical motion into electrical signals sent to the Engine Control Unit (ECU), Instrument Cluster, and other control systems.

As a critical component in modern electronic vehicle management systems, the C03054-20 ensures reliable operation of speedometers, odometers, cruise control, ABS (Anti-lock Braking System), and fuel efficiency monitoring. Built to meet OEM standards, it offers high durability, stable signal output, and resistance to harsh environmental conditions such as vibration, moisture, and temperature extremes.
