Toyota RAV4 Service Manual: Torque sensor
Description
The torque sensor converts the rotation torque input from the steering wheel into electric signals and sends them to the power steering ecu.
Wiring diagram
Inspection procedure
- Check connector connection condition (torque sensor - ecu)
- Check the installation condition of the torque sensor connector.
Ok: torque sensor connector is securely installed to the power steering ecu.
Result 
- Reconfirm dtc
- Reinstall the torque sensor connector.
- Check for dtcs.
Ok:
dtc is not output. 
- Inspect torque sensor
- Turn the ignition switch on.
- Measure the voltage of the ecu.

Hint:
If any dtcs are displayed during the dtc check, inspect the
circuit listed for these dtcs. For details of each dtc, refer to
the page indicated in the dtc chart.
