Toyota RAV4 (XA40) 2013-2018 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.

Symptom confirmation and diagnostic trouble code
Hint:
The diagnostic system in the rav4 has various
functions.
The first function is the diagnostic trouble code
(dtc) check. A dtc is a code stored in the ecu
memory whenever a malfunction in the signal circuits
to the ecu occurs. In a dtc check, a previous
malfunction's dtc can be ch ...
