Intake air

Diaphragm

Mass  airflow  sensor  is  installed  in  the  air  intake  hose.  Mass
airflow sensor is composed of an extremely small heatsensing
resistor. The mass airflow sensor controls the amount of electric
current flowing into the heat sensing resistor to keep the heat
sensing  resistor  at  a  constant  temperature  to  the  intake  air
temperature. The faster the air flow speed, the higher the mass
flow  rate.Because  the  amount  of  heat  transfer  from  the  heat
sensing  resistor  to  the  air  increases,  the  mass  airflow  sensor
increases  the  amount  of  electric  current  to  the  heat  sensing
resistor.  Thus,  the  amount  of  electric  current  increases  in
accordance with the air mass flow rate. The mass airflow sensor
measures  the  air  mass  flow  rate  by  detecting  the  amount  of
electric current. The mass airflow sensor amplifies the detected
electric current amount and outputs it into the ECM. ECM uses
this  output  current  and  engine  speed  to  calculate  and  decide
basic fuel injection time. Sensor properties are as shown in the
figure.

INTAKE AIR TEMPERATURE SENSOR

Sensory part
(thermistor)

Intake  air  temperature  sensor  is  built  in  to  the  mass  airflow
sensor.  Intake  air  temperature  sensor  detects  intake  air
temperature through thermistor's resistance change and outputs
the voltage according to intake air temperature to ECM. ECM
uses this output voltage to compensate fuel injection control and
ignition  timing  control.  Sensor  properties  are  as  shown  in  the
figure.

Manifold absolute
pressure sensor

The manifold absolute pressure sensor is installed in the intake
manifold  plenum.  Manifold  absolute  pressure  sensor  uses  a
piezo resistive semiconductor to output the voltage according to
manifold  absolute  pressure  to  ECM.  ECM  uses  this  output
voltage  to  compensate  fuel  injection  volume  according  to
manifold absolute pressure. Sensor properties are as shown in
the figure.

ENGINE COOLANT TEMPERATURE SENSOR

ZK600238AA00

Sensory part
(thermistor)

Thw  engine  coolant  temperature  sensor  is  installed  in  the
thermostat  housing.  Engine  coolant  temperature  sensor  uses
thermistor's  resistance  change  to  detect  coolant  temperature
and output the voltage according to coolant temperature to ECM.
ECM  uses  this  output  voltage  to  appropriately  control  fuel
injection  volume,  idle  speed  and  ignition  timing.  Sensor
properties are as shown in the figure.
