THROTTLE POSITION SENSOR

ZK603447 AA00

Throttle body

Throttle
position
sensor

The throttle position sensor is installed in the throttle body.
Throttle position sensor outputs voltage to ECM based on the
throttle shaft rotation angle. ECM uses this signal to detect the
throttle valve opening angle to perform throttle actuator control
motor feedback control. This throttle position sensor uses Hall
IC and is a non-contact type.

To ECM

Throttle position sensor is composed of a permanent magnet
fixed on the throttle shaft, Hall IC that outputs voltage according
to magnetic flux density and a stator that efficiently introduces
magnetic flux from the permanent magnet to Hall IC.

Hall IC

Magnetic flux density at Hall IC is proportional to the output
voltage.
Throttle position sensor has 2 output systems - throttle position
sensor (main) and throttle position sensor (sub), and the output
voltage is output to ECM. When throttle valve turns, output
voltage of throttle position sensor (main) and throttle position
sensor (sub) changes. This allows ECM to detect actual throttle
opening angle. ECM uses this output voltage for throttle actuator
control motor feedback control. Also, ECM compares output
voltage of the throttle position sensor (main) and throttle position
sensor (sub) to check for abnormality in the throttle position
sensor. The relationship between throttle opening angle and
output voltage of the throttle position sensor (main) and throttle
position sensor (sub) is as shown in the figure below.

connector

Accelerator pedal arm

Accelerator pedal position sensor is integrated with accelerator
pedal, and detects accelerator opening angle. ECM uses the
output voltage of this sensor to control appropriate throttle valve
opening angle and fuel injection volume. This accelerator pedal
position sensor uses Hall IC and is a non-contact type.

The accelerator pedal position sensor has 2 output systems -
accelerator pedal position sensor (main) and accelerator pedal
position sensor (sub), and the output voltage is output to ECM.
According to depression of the accelerator pedal, output voltage
of the accelerator pedal position sensor (main) and accelerator
pedal position sensor (sub) changes. This allows ECM to detect
the actual accelerator pedal depression amount. ECM uses
accelerator pedal position sensor (main) output voltage for
appropriate throttle valve opening angle control and fuel injection
volume control. Also, ECM compares output voltage of the
accelerator pedal position sensor (main) and accelerator pedal
position sensor (sub) to check for abnormality in sensor. The
relationship between accelerator opening angle and output
voltage of the accelerator pedal position sensor (main) and
accelerator pedal position sensor (sub) is as shown in the figure
below.
