• Hall element sensor has been adopted for the detecting element. With the adoption of a non-contact type sensor, durability is improved.
• The APP sensor has the main and sub sensors, and the accelerator opening angle is detected by both the main and sub systems.
• Even if one of the sensors is malfunctioning, the correct opening angle can be detected.
