piezoresistivity is

• current flow through the thermistor can be used to give an accurate representation of temperature.
• The sensor produces a voltage which is related to throttle position.
• As manifold pressure is applied, the detecting resistors' resistance varies proportionately.
• This capsule is placed in a chamber which is connected to manifold pressure

Throttle Position Sensor

• based on the principle of the Pressure Diffrence
• based on the principle of the potential divider.
• based on the principle of the voltage Diffrence
• based on the principle of the Electro chemical

Phototransistor is used in

• Above all true

A throttle position sensor has ________.

• A.A 5-volt reference input terminal.
• B.A 0 to 5-volt signal output terminal.
• C.A ground terminal.
• D.All these answers are correct.

The mass airflow (MAF) sensor measures the flow of air entering the engine. This measurement of intake air volume is used to calculate engine load (throttle opening and air volume)

• True
• False
