Importance of a Reliable Speed Sensor

The speed sensor is a critical component in any vehicle's transmission system. It plays a vital role in ensuring your car operates smoothly and provides accurate data for optimal fuel efficiency and safety. Speed sensors are part of the vehicle's onboard diagnostic system and relay speed information to the electronic control unit (ECU) of the car.

How the Speed Sensor Functions ⚙️

The speed sensor works by measuring the rotational speed of the wheels or transmission. It detects the electromagnetic signals generated by the teeth in the tone wheel or ring gear, converting them into electronic signals that are then sent to the ECU. This information is essential for various functions such as ABS, traction control, and cruise control systems.

Consequences of a Faulty Speed Sensor ?

If the speed sensor fails, a myriad of issues may arise. The vehicle's transmission may perform erratically or slip, causing a jerky driving experience. Your speedometer may also provide inaccurate readings, impacting the overall driving safety. Additionally, faulty sensors can lead to increased fuel consumption and even impede the activation of crucial safety systems like the ABS.
