1. The lifespan of an air flow meter in a car is generally several years. The car bureau believes that the lifespan of an air flow meter does not have a fixed replacement period, usually around 80000 to 150000 kilometers, but this is not absolute. 1. Environmental impact: If you frequently drive in congested road conditions and frequently start and stop the engine, the impact and wear on the air flow meter will be relatively large, which may shorten its service life. For example, vehicles commuting during rush hour in big cities may need to pay attention to the working status of the air flow meter after 50000 to 100000 kilometers.
2. Oil quality: Adding low-quality fuel, impurities, etc. may cause damage to the air flow meter. If you consistently use high-quality fuel, the lifespan of the air flow meter may be slightly longer; On the contrary, if you frequently add low-quality and low-noise oil, you may need to check or replace it after 30000 to 80000 kilometers. Vehicle maintenance: Regular comprehensive maintenance of the vehicle, including cleaning the air filter, can reduce impurities entering the air flow meter and help extend its lifespan. If not maintained for a long time, the air flow meter may malfunction earlier, and may need to be replaced around 100000 kilometers. Speculatively speaking, if your vehicle has a good operating environment, high oil quality, and proper maintenance, it is also possible for the air flow meter to be used for more than 150000 kilometers; But if the usage conditions are harsh, replacement may need to be considered after about 80000 kilometers.

2. Symptoms of a broken car air flow meter

When a car air flow meter is damaged, the vehicle may experience unstable i

dle, increased fuel consumption, weak acceleration, and worsening exhaust emissions. However, the vehicle can still be driven after the air flow meter is damaged.. Here is a specific analysis: When the air flow meter is damaged due to unstable idle, it may not be able to accurately measure the amount of air entering the engine, resulting in the ECU being unable to accurately control the fuel injection amount. This can cause fluctuations in engine idle speed, making the vehicle run unstably. 2. Increased fuel consumption. Due to inaccurate signals from the air flow meter, the ECU may inject fuel excessively or insufficiently, which can lead to abnormal fuel consumption. 3. Weak acceleration. When the driver steps on the accelerator, if the air flow meter cannot accurately reflect the actual intake amount, the ECU may control the fuel injection amount based on incorrect information, resulting in insufficient engine power and slow vehicle acceleration. Although a damaged air flow meter can affect engine performance and fuel economy, it usually does not directly cause the vehicle to fail to start. Because the amount of fuel required for vehicle start-up is relatively small, and the ECU may use preset start-up programs or backup fuel injection modes to control the fuel injection during the start-up process. Therefore, even if the air flow meter is damaged, the vehicle may still be in motion. However, in order to maintain the normal operation and performance of the engine, timely repair of damaged air flow meters is necessary.
