Component Description For Intake Coolant Temperature Sensor - Mercedes-Benz OM 471 Introduction Into Service Manual

GF20.00>W>4110H
ENGINE 471.9 in MODEL 963
Location
Shown with code (M5Z) Euro VI engine
version
B607 Intake coolant temperature sensor
The intake coolant temperature sensor
(B607) is located under the coolant pump
on the oil/coolant module.
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.
Design
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.

System components
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 (MCM) control unit (A4)
deduces the associated temperature from the electrical resistance.
