Frequently Asked Questions
Question
Engine coolant temperature sensor
Answer
Engine coolant temperature sensor (1220)
The engine coolant temperature sensor informs the ECU about the engine coolant temperature .
Role of the injection ECU according to the data received :
To adjust the starting flow
To adjust the idle speed
To obtain an accelerated idle speed which decreases as the engine heats up
Description
The sensor consists of a CTN -type resistor (negative temperature coefficient resistance) .
The more the temperature increases, the more its resistance value is reduced .
Electrical features
Supply : Injection ECU .
Allocation of the connector channels :
Channel 1 : Signal
Channel 2 : Earth
Electrical specifications :
Resistance at 20 °C = 6250 ohms
Resistance at 80 °C = 600 ohms
