2. Explanation: APS sensor is an electronic device, which is used to measure and report the position of the accelerator pedal, so as to control the engine air supply of the automobile. It is an important part of modern automobile electronic control system, especially in electronic throttle control system. It converts the pressure exerted by the driver on the pedal into an electrical signal, and then sends it to the computer system of the vehicle, so as to control the mixing ratio of fuel and air and further affect the acceleration performance of the vehicle.
3. Extended content: If the APS sensor fails, it may lead to abnormal engine acceleration, unstable idle speed and increased fuel consumption. In addition, when the APS sensor fails, some vehicles will display fault warning lights on the dashboard. If your vehicle has the above problems, you may need to check or replace the APS sensor.
The above information applies to most cars, but the specific location may be slightly different for different models. Therefore, it is recommended that you refer to the owner's manual of the vehicle or contact the automobile manufacturer for more accurate information.
