Torque Sensor and Its Circuit Inspection

Torque Sensor and Its Circuit Inspection
1. Check that torque sensor circuit is in good condition. If check result is not satisfactory, repair torque sensor circuit.
2. Remove console box.
3. With ignition switch turned OFF, connect scan tool to DLC or connect voltage tester between "E11-18"-"E11-9" (main sensor) or "E11-10"-"E11-9" (sub sensor) with connected connector to P/S control module.








4. Set torque wrench to steering wheel for checking steering force.




5. Turn ON ignition switch without engine running and select scan tool "Data List" mode due to checking "TQS Main Torque" and "TQS Sub Torque" displayed on scan tool when steering wheel turned left and right (if used).
6. Check that characteristic of torque sensor (main and sub) output voltage or scan tool data and steering force is as following graph when steering wheel is turned left and right. If sensor voltage or scan tool data is out of specified value or does not vary linearly as the following graph, check EPS control module and its circuit.
If they are OK, replace steering gear case assembly.
