3-12 ENGINE CONTROL SYSTEM
CYLINDER TEMPERATURE SENSOR
The cylinder temperature sensor is installed on the cylinder (top
side) and 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 injec-
tion time duration, ignition timing, evaporation purge system,
etc.
This sensor is also used to detect engine over-heat as the ECM
detects both the temperature and temperature change gradient
(temperature rise vs time).
EXHAUST MANIFOLD TEMPERATURE SENSOR
Two exhaust manifold temperature sensor are used, one
installed on each exhaust manifold (PORT and STBD) and used
to detect exhaust manifold temperature.
This sensor is the same type as the cylinder temperature sen-
sor, and inputs a signal to the ECM as a voltage value.
This signal is also used to detect engine over-heat and control
evaporation purge system.
