- 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.

- Replacement

• Replace the Intelligent Variable Transmission (IVT) assembly as a whole when replacement of inner parts of the IVT is required, Otherwise, dust or foreign substance may get into the IVT during disassembly, which may adversly affect its quality.

1.Replace the IVT assembly.(Refer to Intelligent Variable Transmission (IVT) System - "Intelligent Variable Transmission (IVT)")
