Engine Sensors exercise

What is the purpose of the coolant sensor?

• To monitor the temperature of the engine coolant

• To measure the volume of air entering the engine

• To detect engine vibrations indicating detonation

• To monitor vehicle speed

Which sensor is responsible for monitoring the amount of unburned oxygen in the exhaust?

• Coolant sensor

• Throttle position sensor

• Oxygen sensor

• Knock sensor

What does the oxygen sensor's output signal indicate when the fuel mixture is rich?

• High voltage

• Low voltage

• No voltage change

• Open or closed reading

Where is the MAP sensor typically mounted?

• On the cylinder head or intake manifold

• Ahead of the throttle body

• On the transmission or speedometer head

• On the crankshaft or harmonic balancer

What does the throttle position sensor (TPS) monitor?

• Engine load, acceleration, deceleration, and idle or wide open throttle

• Volume of air entering the engine

• Engine vibrations indicating detonation

• Barometric pressure and changes in altitude

Where is the MAF sensor typically mounted?

• On the cylinder head or intake manifold

• Ahead of the throttle body

• On the transmission or speedometer head

• On the crankshaft or harmonic balancer

What type of sensor is used on Bosch and other import multiport fuel injected engines?

• Coolant sensor

• Throttle position sensor

• Oxygen sensor

• Vane airflow sensor

What does the manifold air temperature (MAT) sensor monitor?

• Engine load, acceleration, deceleration, and idle or wide open throttle

• Volume of air entering the engine

• Incoming air temperature

• Barometric pressure and changes in altitude

What is the purpose of the crankshaft position (CKP) sensor?

• To monitor the temperature of the engine coolant

• To measure the volume of air entering the engine

• To determine the position of the crankshaft and the number one cylinder

• To detect engine vibrations indicating detonation

What does the knock sensor detect?

• Engine vibrations indicating detonation

• Changes in altitude and barometric pressure

• Vehicle speed

• Incoming air temperature
