ACCELERATOR PEDAL POSITION (APP) SENSOR CONSTRUCTION/OPERATION [LF]
E5U014041609N02
• The sensor is installed on the accelerator pedal and detects how much the accelerator pedal 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).
• The main sensor output a duty signal, and the sub
sensor output a voltage signal.
• 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.
