Subaru Transmission Speed Sensor

Subaru Transmission Speed Sensor

How Does a Transmission Speed Sensor Work?

The operation of a transmission speed sensor involves detecting the rotational speed of the transmission shafts and converting these into an electrical signal. Here’s a simplified breakdown of its operation:

  1. Sensing Element: The core component is typically a magnetic or hall-effect sensor placed near a toothed wheel or gear on the transmission shaft.
  2. Speed Detection: As the shaft rotates, the teeth or notches on the wheel pass by the sensor, causing fluctuations in the magnetic field.
  3. Signal Generation: These fluctuations are converted into an electrical signal that corresponds to the rotational speed of the shaft.
  4. Data Transmission: This signal is sent to the TCU and ECU, which use it to determine the precise timing for gear shifts and other transmission functions.
