The following statements pertain to the throttle position sensor. Select the statement that is True.Group of answer choicesFor the throttle position sensor without an IDL contact, the engine ECU uses the VTA signal to perform learned control and detect idling condition.For the throttle position sensor without an IDL contact, the engine ECU receives the IDL signal from other ECUs to control.The throttle position sensor outputs the VTA signal step by step in accordance with the throttle opening angle.For the throttle position sensor without an IDL contact, the engine ECU determines 0 V position of the VTA signal as the idling condition.

The engine ECU always determines the proper fuel injection volume based on the signals from various sensors.Group of answer choicesTrueFalse

Signals sent from sensors to the engine ECU are the amount of current.Group of answer choicesTrueFalse

The following statements pertain to the speed sensor. Select the statement that is True.Group of answer choicesSome vehicle models use the SPD signal of the ABS ECU as the speed signal.In the MRE type speed sensor, the SPD signal is converted into the digital signal in the combination meter.The speed signal goes through the combination meter surely to operate the speedometer.The speed sensor measures the crankshaft rotational speed of the engine.Next

The following statements pertain to the water temperature sensor and intake air temperature sensor. Select the statement that is True.Group of answer choicesWhen the circuit of the built-in thermistor opens, the sensor terminal voltage in the engine ECU becomes 0 V.The water temperature sensor is turned on when the coolant temperature becomes high.The intake air temperature sensor measures the density of the intake air.As the coolant or intake air temperature are low, the sensor terminal voltage in the engine ECU becomes high. Conversely, the sensor terminal voltage becomes low as temperature are high.

If the pitch control lever on a normally aspirated engine fitted with a CSU is moved to decrease RPM with no adjustment made to the position of the throttle, the manifold pressure willQuestion 29Select one:a.Remain unalteredb.Increasec.Decreased.Increase then decrease
