THw - Thermistor water
ECT - Engine Coolant Temperature
Does the sensor meet the manufacturer's why or why not?
Yes, the resistance dos meet the manufacturer's specifications with the temperature change. Specifications are 2-3kilo ohms when it is cold and 200-400 ohms when it is hot.
What type of thermistor is this?
This is a water temperature sensor of toyota and it NTC.
Explain the internal operation of the sensor?
It measures engine coolant temperature which changes its resistance. If the resistance increases with coolant temperature then it is the PTC whereas if the resistance decreases with coolant temperature then it is NTC.
