Digital Diesel Electronics, Dde 2.1 Coolant Temperature Sensor Opel Omega B

Coolant Temperature Sensor

The coolant temperature sensor (1) determines the coolant temperature in the cylinder head and communicates the values as influencing variables to the control unit DDE 2.1.

The coolant temperature sensor is an NTC resistor, which decreases the resistance as the temperature increases.

The inner resistance is approx. 2.2 kW at 20 °C / 68 °F
