Coolant inlet temperature sensor, component description

Location
The intake coolant temperature sensor (B607) is located under the coolant pump on the oil/coolant module.

Shown on engine 471.9, engine version Euro VI Standard

B607

Intake coolant temperature sensor

W20.00-1052-06

Task

The coolant inlet temperature sensor (B607) enables the engine management (MCM) control unit (A4) to determine the current coolant temperature downstream of the coolant pump.

Structure

There is an NTC resistor inside the intake coolant temperature sensor (B607). NTC stands for "Negative Temperature Coefficient", which means that electrical resistance falls as temperature rises.

Function

The coolant at the intake coolant temperature sensor (B607) influences the temperature measuring element inside the sensor depending on its temperature and thus the size of the electrical resistance. The engine management control unit (MCM) (A4) derives the associated temperature from the electrical resistance.
