肮脏的空气过滤器确实会导致检查发动机灯亮起. 空气滤清器在车辆发动机的功能中起着至关重要的作用. 它的主要功能是防止污垢, 碎片, 和其他污染物进入发动机并造成损坏. 然而, 随着时间的推移, 空气过滤器可能会被灰尘和碎片堵塞, 降低其有效性.

当空气过滤器脏污或堵塞时, 它限制了发动机的气流, 产生丰富的空气燃料混合物. 这种不平衡会触发检查发动机灯亮起. 发动机控制单元 (电子控制单元) monitors various sensors and parameters to ensure the engine is running optimally. If it detects a problem with the air-fuel mixture due to a dirty air filter, it will illuminate the check engine light to alert the driver.

In addition to triggering the check engine light, a dirty air filter can also negatively impact the performance and fuel efficiency of the vehicle. Restricted airflow can lead to reduced power output, sluggish acceleration, 以及油耗增加. 所以, it is important to regularly inspect and replace the air filter as recommended by the vehicle manufacturer.

Fortunately, replacing an air filter is a relatively simple and inexpensive maintenance task. Most air filters can be easily accessed and replaced without the need for specialized tools. It is generally recommended to replace the air filter every 12,000 至 15,000 miles or as specified in the vehicle’s owner’s manual.

Regular maintenance and timely replacement of the air filter can help prevent the check engine light from coming on due to a dirty air filter. It is also important to note that a dirty air filter is just one of the many potential causes for a check engine light. If the check engine light remains illuminated even after replacing the air filter, it is advisable to have the vehicle diagnosed by a qualified mechanic to determine the underlying cause.
