Description and Operation

Description

  • The speed sensor is integrated into the E-module.

  • The speed sensor uses an electric current type Hall sensor, in which the current is changed

  • The speed sensor measures the rotational speed of the input and output shafts inside the transmission and sends the readings to the TCM.

  • The sensor provides important inputs used in feedback control, torque converter clutch control, shift control, line pressure control, clutch pressure activation control, and sensor malfunction analysis.
