Toyota RAV4 (XA40) 2013-2018 Service Manual: Motor rotation angle sensor malfunction
Description
The motor rotation angle sensor detects the motor rotation angle and sends this information to the power steering ecu.
Wiring diagram
Inspection procedure
- Check connector connection condition
- Check the installation condition of the motor rotation angle sensor connector.
Ok: motor rotation angle sensor connector is securely connected to the power steering ecu.
Result 
- reconfirm dtc
- Reinstall motor rotation angle sensor connector.
- Check for dtc.
Ok: dtc is not output.
Result 
- Read value of intelligent tester (motor rotation angle sensor)
- Connect the intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch on and press the intelligent tester main switch on.
- Select the items "motor rotate" in the data list
and read the value displayed on the intelligent tester.
Ok: during steering operation, motor rotation angle value changes from 0 to 360м/b>

Oxygen sensor circuit
Description
In order to obtain a high purification rate of the carbon monoxide (co),
hydrocarbon (hc) and nitrogen
oxide (nox) components in the exhaust gas, a twc is used. For the most efficient
use of the twc, the
air-fuel ratio must be precisely controlled so that it is always close to ...
