SFI SYSTEM DETAILS ACCELERATOR PEDAL SENSOR

  1. CONSTRUCTION

    1. The non-contact type accelerator pedal sensor assembly uses a Hall IC.

    2. The magnetic yoke mounted at the base of the accelerator pedal arm rotates around the Hall IC in accordance with the amount the accelerator pedal is depressed. The Hall IC converts the changes in magnetic flux that occur into electrical signals, and outputs them in the form of accelerator pedal input signals to the ECM.

    3. This accelerator pedal sensor assembly includes 2 Hall ICs and circuits for the main and sub signals. It converts the accelerator pedal opening angle into voltage signals with 2 differing characteristics and outputs them to the ECM.

    4. On models with the speed limiter system, when the accelerator pedal opening angle is greater than a predetermined amount, the ECM detects a "kick down mode" request through the VPA signal sent by the accelerator pedal sensor assembly.
