What are the manifestations of internal failure in a Mercedes steering angle sensor?
2 Answers
Mercedes steering angle sensor internal failure manifests as the skid light illuminating on the Mercedes dashboard. Below are detailed descriptions about the Mercedes steering angle sensor: 1. Overview: The steering angle sensor is a device used to detect the rotation angle and direction of the steering wheel. Whether the steering wheel is turned left or right, the steering angle sensor detects it, enabling the vehicle's electronic control unit to issue correct steering commands. The rotation angle of the steering wheel provides the basis for the vehicle's steering amplitude, allowing the car to steer according to the driver's intentions. 2. Composition: The steering angle sensor consists of components such as a photoelectric coupling element and a perforated slot plate. The photoelectric coupling element includes a light-emitting diode and a phototransistor. The perforated slot plate is positioned between the light-emitting diode and the phototransistor.
When driving my Mercedes, I encountered an internal fault with the steering angle sensor. The first sign was the Electronic Stability Program (ESP) warning light on the dashboard staying illuminated, with red or yellow lights flashing, as if alerting me to a system issue. The steering wheel felt imprecise, especially during turns, with delayed or increased play in the steering response. Occasionally, the vehicle would drift slightly at high speeds, making it unstable and prone to lane deviation. This could affect the ABS and traction control systems, increasing the risk of skidding on wet or icy roads. I recommend immediately visiting a professional repair shop for diagnostic computer checks. They can usually read the fault codes and resolve the issue—don’t delay to prevent accidents.
