Is it safe if the car sensor is broken?

[OGrant]

Damage to the car sensor can directly affect driving safety to a certain extent. If the wheel speed sensor is damaged, it not only causes slight deviations in the speed display on the dashboard but also leads to unstable engine idling and reduced acceleration performance. The main sensors in a car are as follows: 1. Airflow sensor: The airflow sensor is usually installed between the air filter and the throttle body to measure the amount of air inhaled by the engine, converting it into an electrical signal provided to the ECU as a reference signal for fuel injection timing. If it malfunctions, the car may experience idling vibrations, weak acceleration, increased fuel consumption, and black smoke from the exhaust pipe, thereby affecting the engine's performance. 2. ABS sensor: The ABS sensor is typically located near the wheel bearing, outside the hub bearing and inside the brake disc, to monitor the vehicle's speed. During emergency braking, it feeds the wheel speed back to the braking system, which then controls the wheel's rotation to achieve optimal braking effect. If it fails, the ABS will not function, causing the wheels to lock up during emergency braking, leading to skidding and loss of control. 3. Throttle position sensor: The throttle position sensor is installed on the throttle body to detect the throttle opening. It works in conjunction with the throttle via a lever mechanism, measuring the throttle opening angle's voltage signal and transmitting it to the ECU as a reference signal for fuel injection volume and ignition timing correction. If it malfunctions, it can result in abnormal engine idling, engine vibrations, and delayed acceleration response.
