Exam 21: Instrumentation and Information Displays

The ____________________ gauge indicates engine speed [RPM].

All the following are items to be checked in gauge systems EXCEPT:

An NTC thermistor is used in a(n) _____.

Technician A says most digital temperature gauges are bar-type displays. The number of illuminated bars varies according to the current flow from the sending unit. Technician B says some warning lights are triggered by the PCM and BCM. Who is correct?

A digital speedometer constantly reads zero mph. Technician A says the problem may be the vehicle speed sensor. Technician B says the problem may be the throttle position sensor. Who is correct?

Analog gauges use digital displays of numbers.

Which of the following is not a type of digital display?

Which of the following is NOT connected to the tone generator [chime module]?

What tools are needed to check the operation of a fuel gauge sending unit?

A heads-up display projects visual images on the ____________________.

Technician A uses a universal gauge tester to diagnose gauge problems. Technician B uses a scan tool to test the ECT [engine coolant temperature] sensor. Who is correct?

The sending unit for the engine coolant temperature gauge is typically an NTC thermistor.

The indicator needle on a speedometer is held to the zero position by ______.

All electrical gauges require an input from either a ____________________ or sensor.

The resistance value of an NTC thermistor ____________________ as temperature increases.

Which of the following is NOT a type of gauge design?

LCDs are usually red, white, or green

On most new vehicles, the action of an ECT [engine coolant temperature] sensor can be monitored on a scan tool.

Most digital speedometers have a speed limit. If the vehicle exceeds the speed value, the speedometer continues to display the top of its range.

Technician A says a cable-driven speedometer unit depends upon magnetism to move the needle. Technician B says the vehicle speed sensor used with an electronic speedometer is typically mounted near one of the vehicle drive wheels. Who is correct?
