Mazda CX-5 Service & Repair Manual: Accelerator Pedal, Kickdown Switch
Purpose, Function
-
The driver's intentions are transmitted to the PCM via the accelerator pedal.
-
Kickdown switch (ATX) (Applied VIN (assumed): JM3 KE2*E*D# 148107?)
-
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?)
