What does the APS button on a car mean?

[DeWillow]

In a car's central control panel, APS stands for Accelerator Pedal Sensor. Below are detailed explanations about the APS in cars: 1. The APS accelerator pedal on the car's central control panel, also known as the throttle pedal, primarily controls the opening of the engine's throttle valve, thereby regulating the engine's power output. 2. The main function of the accelerator pedal is to control the throttle valve's opening, thus managing the engine's power output. In some cars, the accelerator pedal is connected to the engine's throttle valve via a throttle cable or linkage rod. When the driver presses the accelerator pedal, it directly controls the throttle valve.
