p.s. Похоже, что в этой Mazda EPS, а не EHPAS. Т.е.
граната другой системы* ![Wink ;)](./images/smilies/icon_wink.gif)

И для EPS такой Mazda6 a '08 более актуальна эта процедура:
EPS SYSTEM NEUTRAL POSITION SETTING писал(а):
1. Set the front wheels in the straight-ahead position. (Steering wheel is within 45' to the left or right of center position.)
2. Jack up both front tires so that there is no weight on them.
3. Lower the jack until the front tires touch the ground.
Caution. After lowering the jack and placing the vehicle on the ground, do not touch the steering wheel and front tires until the EPS system neutral position setting is completed. Otherwise, the EPS system may not operate normally.
4. Connect the IDS to the DLC-2.
5. After the vehicle is identified, select the following items from the initialization screen of the IDS.
- When using the IDS (laptop PC)
1. Select “Chassis”.
2. Select “EPS”.
3. Select “Neutral Position Setting”.
-When using the PDS (Pocket PC)
1. Select “All Tests and Calibrations”.
2. Select Neutral Position Setting”.
6. Perform the procedure according to the directions on the screen.
7. After setting to neutral, start the engine, rotate the steering wheel slowly in both directions within a range of 90', and verify that the steering force does not differ in either directions.
If the steering force is different in either direction, inspect the power steering system following a separate troubleshooting procedure.
POWER ASSIST DIFFERS BETWEEN RIGHT AND LEFT
Steering gear and linkage malfunction
Steering gear sticking
Tie-rod end sticking
EPS motor malfunction
Torque sensor malfunction
Resolver sensor malfunction
EPS control module malfunction
EPS system neutral position setting not performed
Wheel alignment misadjusted
Front tire condition (air pressure, wear-out condition) different between left and right
p.s.s. Поэтому наряду с версией о том, что "барахлит" датчик момента*, нельзя исключить и "просто слетание" установки нейтрального положения.
* Проверяется по осциллограммам Torque Sensor и, заоодно, Resolver Sensor.
