After the air flow meter of the car rental car is damaged, the vehicle will experience unstable idle speed, and the engine will start slowly and sometimes even stall. Fuel consumption has also significantly increased, and the vehicle may feel less smooth during driving, with weak acceleration and inconsistent power output. In addition, the increase in exhaust emissions has caused more serious pollution to the environment. Automobile air flow meters are mainly divided into four types: blade type, optical Karman vortex, Karman vortex, and ultrasonic Karman vortex. Its function is to detect the intake volume of the engine, convert the intake volume information into an electrical signal, and transmit it to the ECU to help the driver timely understand the working status of the engine. The application range of air flow meters is wide, including industrial production, biotechnology, scientific experiments, environmental protection and other fields. If the vehicle shows the above symptoms, it should be inspected immediately. Normally, a damaged air flow meter can cause the engine management system to be unable to accurately calculate the intake air volume, which in turn affects the fuel injection volume, leading to increased fuel consumption, unstable power output, and other issues. When conducting an inspection, the fault code can be read using a diagnostic tool to confirm if it is a malfunction with the air flow meter. If it is determined that the air flow meter is damaged, it is recommended to go to a professional repair shop for replacement. Replacing the air flow meter is a relatively simple main

tenance task. When selecting new parts, it is important to ensure their compatibility with the vehicle to ensure stable performance and reliability. Before installation, the relevant components and connection ports should be cleaned to ensure a tight and secure connection, in order to avoid further malfunctions caused by poor connections. After replacement, restart the vehicle and use a fault diagnosis instrument with a modem to check if the system is functioning properly, ensuring that the problem is resolved. In order to prevent damage to the air flow meter, it is necessary to pay attention to vehicle maintenance, regularly inspect and replace the air filter, in order to reduce the damage of dust, impurities, etc. to the air flow meter. At the same time, avoid driving in harsh environments for long periods of time, such as flying dust, sandstorms, etc., to protect the engine and air flow meter. Reasonable use of the vehicle during driving, avoiding sudden acceleration, sudden braking, and other operations, can also help extend the service life of the air flow meter.

3. What are the symptoms of damaged car air flow meters? When a car air flow meter malfunctions, a series of obvious symptoms will appear. Firstly, idling can become unstable, which may cause the vehicle to shake or stall when parked or driving at low speeds. Secondly, fuel consumption will increase significantly because the engine cannot accurately measure the intake air volume, thus making it difficult to accurately control the fuel injection amount. In addition, weak acceleration is also a common symptom of air flow meter damage, as the engine cannot obtain sufficient air flow to generate the required power. Finally, exhaust emissions may become
