Purpose, Function
The driver's intentions are transmitted to the PCM via the accelerator pedal.
If the accelerator pedal is depressed carelessly, kickdown control will be implemented based on the accelerator pedal being determined as fully open, and vehicle shock will occur. A kickdown switch has been adopted so that it can be determined that the accelerator pedal is fully open based on the driver’s intention of depressing the accelerator pedal for kickdown.
Construction
The accelerator pedal has a built-in APP sensor and kickdown switch (ATX).

For the APP sensor, refer to CONTROL SYSTEM..
Kickdown Switch (ATX) (Applied VIN (assumed): JM3 KE2*E*D# 148107?)
A load can be felt while the accelerator pedal is being depressed and when it is further depressed the kickdown switch turns on.

The driver can control the kickdown by knowing the amount of accelerator depression.
The kickdown switch is only a measure of the kickdown. An electrical signal is not transmitted by the kickdown switch turning on/off, and vehicle control is not affected.
