What are the effects of a faulty sensor on a car?

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.

As a young person who often drives the family car for outings, sensor issues can really ruin the fun. For example, a faulty crankshaft position sensor can make the car hard to start or even leave you stranded on the road, which would be a real hassle if it happens in the middle of nowhere. A malfunctioning camshaft sensor can cause jerky gear shifts, making the ride as uncomfortable as a roller coaster. If the air quality sensor fails, the AC might blow unpleasant odors, affecting your health. Not to mention when advanced sensors like the lane-keeping assist system stop working, you might not even realize you're drifting on the highway. These issues also increase fuel consumption and exhaust pollution, hitting your wallet hard. In short, sensors are the core of modern cars—one failure can affect the whole system. It's advisable to use an OBD scanner for regular checks to prevent problems.

Having worked in an auto repair shop for over a decade, sensor failures are common jobs that significantly impact vehicles. A malfunctioning oxygen sensor causes excessive exhaust emissions and increases fuel consumption by about 15%. Issues with the ABS sensor double the risk of brake failure. A faulty engine cooling system sensor can lead to uncontrolled coolant temperature, potentially causing cylinder seizure. If the airbag sensor fails, collision protection becomes ineffective, which is a matter of life and death. Some customers don't take it seriously, only to end up with major repairs costing tens of thousands. I recommend seeking professional inspection immediately when the dashboard warning light comes on.
