What are the effects of a faulty sensor on a car?
2 Answers
It may affect the wheel alignment balance of the car, as well as the engine coolant temperature. Below is relevant information about automotive sensors: 1. Classification: Based on their functions, sensors can be categorized into those measuring temperature, pressure, flow rate, position, gas concentration, speed, light intensity, humidity, distance, etc. Once a sensor fails, the corresponding device may operate abnormally or even stop working. 2. Application: Automotive sensors were previously used solely for engines, but now they have expanded to chassis, body, and lighting electrical systems. There are over 100 types of sensors employed in these systems.
I've been driving for over 20 years, and sensor failures can cause significant issues. For example, when the oxygen sensor malfunctions, the engine runs unevenly, the vehicle's power decreases, there's strong jerking during acceleration, and fuel consumption increases by more than 10%. A faulty ABS sensor is even more dangerous—during rainy weather, the tires can easily lock up when braking, increasing the risk of accidents. If the temperature sensor fails, it can lead to the cooling system losing control, potentially causing the engine to overheat and burn out, which could cost thousands to repair. And if the airbag sensor fails, the airbags might not deploy during a collision, which is a matter of life and death. Sensors are like the eyes of a car—if they fail, they need to be checked and repaired promptly. Otherwise, small problems can turn into big troubles. I experienced this myself last year—it took two days at the dealership to fix the issue.
