Cylinder Temperature Sensor
The cylinder temperature sensor is installed on the
cylinder (top side) and is used to detect the cylinder
temperature.
This is a thermistor type sensor (resistance of which
changes depending on temperature) and inputs a signal
to the ECM as a voltage value. This signal is used to
compensate the fuel injection duration, ignition timing,
etc.
This sensor is also used to detect engine over-heat as
the ECM detects both the temperature and temperature
change rate (gradient temp.-temperature rise vs. time).
Exhaust Manifold Temperature Sensor
The exhaust manifold temperature sensor is installed on
the exhaust manifold and used to detect exhaust
manifold temperature.
This sensor is the same type as the cylinder temperature
sensor, and inputs a signal to the ECM as a voltage
value.
This signal is also used to detect engine over-heat.
IAT Sensor
The IAT sensor is installed on the air intake silencer case
and is used to detect the intake air temperature.
This sensor is the same type as the cylinder temperature
sensor, and inputs a signal to the ECM as a voltage
value.
This signal is used to compensate the fuel injection
duration.
