its on the steering collom im not quite sure on the exact location but at a guess it would be down by the brake pedal ?
the thing is
the yaw sensor and steering angle sensor is only used with the abs/esp abs unit
most 2.2's dont have esp unless fitted as an optional extra in opcom it would be abs/tc and not the abs/esp
the abs/esp abs unit has a pressure switch on the front and the normal abs/tc unit has no pressure sensor
also in opcom in the measuring blocks you will see the steering angle sensor readings if it is fitted
