This should explain how it works ,
The Meriva (punto corsa) use a electric motor that is attached to the column using worm and gear set up to drive the main column.
In this set up is a column, motor torque sensor and an ECU. the torque sensor is the biggest failure of the column ( and is the same sensor fitted into the punto). The EPS will and can fail switching off the assistance which can be very unnerving.
