Choose the correct TWO (2) types of this signal
Cardiovascular Signal
Inductive Signal
Pulse Width Modulation (PWM)
Digital Signal
Analog Signal
Choose the correct TWO (2) types of this signal
Inductive Signal
Pulse Width Modulation (PWM)
Analog Signal
Sine Wave Signal
Digital Signal
Figure shows a voltage signal from an Accelerator Pedal Position (APP) Sensor. Choose the correct type of this signal.
Sine Wave Signal
Analog Signal
Pulse Width Modulation (PWM) Signal
Digital Signal
Inductive Signal
Figure shows a voltage signal from an Accelerator Pedal Position (APP) Sensor. This sensor provides two signals to the Engine Control Unit (ECU). Why this is necessary?
Provides substitute if another signal fail.
Combination of two low voltage signal is needed to produce high voltage signal.
Provides safety precaution if one of both signals fail.
Both signal are use alternately during long travel period to avoid sensor overheat.
One signal is used during eco-mode driving and dual signal is used during sport-mode driving.
