23387863 Speed Sensor — Volvo FH12 FH16

This speed sensor monitors the rotational speed of the transmission or driveshaft, providing critical data to the engine control unit (ECU) for optimal performance. It is built with precision to accurately measure speed variations, ensuring correct gear shifting and fuel management, unlike a worn sensor that provides erratic or no signal. Operators may observe incorrect speedometer readings, transmission shifting problems, or illuminated check engine lights.

Failure Symptoms

A failing speed sensor can initially cause intermittent inaccuracies in the speedometer or erratic transmission shifting. If the sensor fails completely, the speedometer will stop working, and the transmission may default to a 'limp home' mode. Continued operation without a functioning speed sensor can lead to poor fuel economy and potential damage to the transmission.

Installation Tip

Ensure the sensor mounting surface is clean and free of metal shavings before installation. Do not overtighten the sensor, as this can damage the threads or the sensor itself.

Service Note

Check the wiring harness and connectors for any signs of damage or corrosion, and inspect the transmission fluid level and condition.
