An _______ number of sensor types exist to measure various types of data required by increasingly sophisticated commercial vehicle control systems.

• small

• large

• enormous

• All of the above

Common sensor applications include the following

• Accelerometers for vehicle dynamic control and airbags

• Pressure sensors for engine oil, fuel, crankcase, and intake boost

• Position sensors for wheel speed, camshafts, crankshafts, and pedal position

• All of the above

GPS stands for?

Virtual sensors using software algorithms to estimate a physical value that is practical or possible to directly measure

• True

• False

Active sensors use current supplied by the ECU to operate an internal __________, signal conditioning circuit while passive sensors do not.

• switch

• transducer

• passive

• active

The simplest digital signal is a single pole single throw (SPST) switch. It is found in either an open or closed state.

• True

• False

When the switch is connected between the ECU and a battery positive, the switch is known as a pull-down switch.

• True

• False

A pull-up switch is connected between the ECU and a negative ground current potential.

• True

• False

When voltage drop measurements are abnormally high or low when the switch is expected to be either opened or closed, the _____________ logs the appropriate fault code.

• Microprocessor

• Micrometer

• Microcontroller

• Micro switch

Kirchhoff ’s Law states the sum of the voltage drops in a series circuit equals source voltage.

• True

• False
