ACCELERATOR PEDAL POSITION (APP) SENSOR CONSTRUCTION/OPERATION
CHU014041600S02
•
The sensor is installed on the AP and detects how much the AP is depressed.
•
The Hall element design has been adopted on the
sensor.
•
A non contact type sensor has been adopted to
improve durability.
•
The APP sensor is composed of the main sensor
and sub sensor, and detects the accelerator
opening angle with these two sensors (main and
sub).
•
Even if a malfunction occurs in either one of the
sensors, the detection is performed with a normal
sensor drive-by-wire control is maintained.
•
If both the MAIN and SUB sensors for the APP
sensor malfunction, signals necessary for the
drive-by-wire control are not input to the PCM and
the drive-by-wire control is disabled.
•
However, even though the drive-by-wire control is
disabled, the throttle valve opening angle
necessary for minimum driving is maintained
mechanically.
