ENGINE COOLANT TEMPERATURE SENSOR:

This temperature sensor has a variable resistance
which decreases with the increase in temperature.
The ECU provides the sensor with a +5 Volt signal
and measures the corresponding current, thus
calculating the temperature,
characteristics of the sensor.
Each of the cylinders has one of these sensors,
although only one of them is connected to the ECU
(the other is connected to the control panel).
