Car sensor damage is serious. If the idle control-related sensors in the car are broken, it will affect the vehicle's startup. Below are the fault causes and solutions: 1. Unstable engine idle; momentary stalling or engine shutdown when starting the vehicle or decelerating to stop; reduced engine acceleration performance; deviation in the speed display on the dashboard; engine warning light turns on. 2. External force tearing the wheel speed sensor wiring harness: The equipped wheel speed sensor wiring harness lacks reserved length, leading to frequent tearing when turning the wheel to full lock. The issue can be resolved by modifying the wheel speed sensor bracket to create a reserved length for the wiring harness, preventing future damage after replacement. 3. Dirty sensor heads or contamination by magnetic substances can cause wheel speed sensor failure. If the wheel speed sensor frequently malfunctions after driving through water, muddy roads, sandy paths, etc., it is likely due to dirt and requires cleaning.

What is the function of Mercedes-Benz's negative ions?

Mercedes-Benz's negative ions serve to purify the air, improve sleep, and prevent respiratory diseases. Purifying the air: Negative ions themselves carry a negative charge and exhibit negative electrical properties. When negative ions encounter particles such as dust in the air, the positive and negative charges attract each other, causing the dust and other substances to clump together, increasing their weight and causing them to settle on the ground. Improving sleep: Negative ions are a natural factor that has a beneficial effect on improving sleep. Preventing respiratory diseases: Negative oxygen ions can effectively enhance the ciliary movement of the tracheal mucosal epithelium, influence the activity of respiratory enzymes in the epithelial villi, and improve the secretory function of the alveoli as well as the ventilation and gas exchange functions of the lungs.
