What are the effects of a faulty brake sensor on a car?
2 Answers
It can cause poor acceleration, unstable idling, and poor engine performance. It is recommended to repair the issue promptly. Below is information about other sensors: Intake pressure sensor: When faulty, the engine's intake pressure becomes abnormal, and the car's computer cannot receive the correct signal, leading to abnormal fuel injection. This results in incomplete combustion of gasoline in the cylinder, causing black smoke during acceleration and a lack of engine power. Coolant temperature sensor: If there is a problem, the car detects abnormal coolant temperature signals during operation. The car's computer will then control the engine's power output to protect the engine. The engine fault indicator on the dashboard will light up, and the engine computer will limit the engine's output, resulting in a lack of power.
A while ago, the brake sensor in my car malfunctioned, causing the brake warning light on the dashboard to stay lit while driving, which made me quite uneasy. Every time I braked, the response felt delayed, and the pedal felt softer than usual, lacking its usual crispness. Especially on rainy days, the tires tended to lock up when turning on slippery roads, almost causing the car to slide out of the lane. Later, at the repair shop, the mechanic explained that this sensor monitors brake fluid pressure and pedal position, and if it fails, it can disable the ABS system, significantly increasing the risk of losing control during emergency braking. Fixing it wasn’t too troublesome—replacing the sensor cost a little over 200 yuan and took just half an hour. The lesson here is not to ignore these small warning signs. The car is a lifeline, and regular check-ups are essential for safe travels.
