Steering Angle Sensor: Service and Repair

Removing and installing steering-angle sensor
General information
The steering-angle sensor is integrated into the - steering column switch.





The steering angle is recorded in the contact unit for airbags (spiral spring) -C-. The sensed data is sent from the electronic unit -E- via the drive CAN bus to various systems (e.g., PSM, corner-sensitive headlight) for further processing. Replacement of the steering angle sensor requires the steering column switch to be removed.
If faults have been diagnosed on the steering-angle sensor, the steering column switch must be disassembled into the components -A, B, C, D, E-.
It is only permissible to replace the steering-angle sensor as the combination of the components contact unit for airbag -C- (spiral spring) and electronic unit -E-.





Replacing the steering-angle sensor





1. In order to replace the steering angle sensor, the components contact unit for airbag -C- and the electronic unit -E- must be replaced.
2. Once installed, the steering angle sensor must be calibrated with the Porsche System Tester PSM.
