Steering Angle Sensor

The electronic steering is from a Corsa B, which, over time, suffers from the dreaded “Corsa Steering Angle Sensor Problem", making the car constantly pull to one side. 

The video by EasySteer, where I got the kit, shows how to fix this issue. Corsa Steering Angle Adjustment 

The steering angle sensor box can be seen below next to the electric steering motor. 

The write-up for the process is below: 

  • Get the front off the ground and remove the wheels.
  • When the ignition is turned on, the Electronic Power Steering (EPS)will drive the steering column depending on the reading of the torque sensor.
  • If the position sensor is misaligned, the wheel will be driven continuously in one direction when the ignition is switched on.
  • The column has a position sensor at the top behind the steering wheel that will count 30 turns from end to end before it jams. 
  • Remove the sensor cover.
  • Turn the wheel back to the centre.
  • Turn on the ignition, the steering wheel may spin rapidly. Switch off if it does. 
  • Rotate the torque sensor fractionally and turn on the ignition again. 
  • Repeat this process until the steering is still when the ignition is on.
  • Then, give the steering wheel a short tug in one direction and let it settle, then do the same in the other direction. 
  • The wheel may continue a little or might bounce back a little. Adjust the torque sensor position until the behaviour is identical in both directions if necessary.
  • Repeat the torque sensor setting procedure to ensure the behaviour is identical in both directions. Adjust if necessary. When you are satisfied that the steering is balanced and neutral, turn off the ignition and tighten the sensor retaining screws.
  • Refit the Sensor cover, and re-assemble dash covers and screws.
