حساس زاوية التوجيه معيب

The sensor reporting how far and how fast the steering wheel is turned. Stability control is meaningless without it, because the whole intervention is a comparison between where the driver is pointing and where the car is actually going.

Calibration is the first thing to eliminate and it is not a formality. The sensor measures angle relative to straight ahead and must be told where that is. An alignment, a rack, a clock spring, a battery disconnection or a module swap all lose the reference — leaving a healthy sensor reading wrong.

The clock spring is the second. The sensor sits behind the steering wheel and its signals pass through the coiled ribbon cable that also carries the horn and the airbag. That ribbon is a wearing part. An airbag warning light alongside a steering angle code points there rather than at the sensor.

The sensor itself is usually the last answer, and on many vehicles it is not separately available — it comes as part of the clock spring assembly, which is worth knowing before pricing the job.
