Description
(1) coolant temperature sensor
"a" 2-way black connector
Supplier: ELTH
The sensor is a resistive, negative temperature coefficient (CTN), sensor
Role
The engine coolant temperature sensor informs the engine ECU of the temperature of the engine coolant fluid
Function
The NTC (Negative Temperature Coefficient) resistance value changes in relation to the change in the temperature
- When the temperature increases, the resistance value decreases
- When the temperature decreases, the resistance value increases
