- Description

Drive Pulley Speed Sensor

• Drive pulley sensor is integrated into the E module.

• The sensor detects the rotation speed of the drive pulley in the Intelligent Variable Transmission (IVT) and transmits it to TCM

Turbine Speed Sensor

• Turbine speed sensor is integrated into the E module.

• Turbine speed sensor detects the speed of the turbine in the IVT and transmits it to TCM.

Oil Temperature Sensor

• Oil temperature sensor is integrated into the E module.

• Oil temperature sensor detects the Intelligent Variable Transmission Fluid (IVTF) temperature and transmits it to TCM.
