Coolant temperature sender

The coolant temperature sender is located on the 
connection coupling for the coolant above the 
coolant pump. 

Its signal serves as a variable for determining the 
engine temperature and for detecting whether 
preheating, post-heating, standby heating or 
increased idle speed is required when the engine 
is cold (90 sec). 

The signal is additionally used in the event of 
engine overheating to reduce the power output. 

Functional description

The coolant temperature sender features an NTC 
bead. An NTC (

N

egative 

T

emperature 

C

oefficient) changes its resistance corresponding 

to temperature. When the temperature increases 
the resistance value drops. When the 
temperature drops the resistance values 
increases. 
The engine control unit can detect the current 
engine temperature from this resistance value. 

Substitute function

If the engine control unit receives no signal from 
the coolant temperature sender, a fixed value 
stored in the engine control unit is used as the 
substitute signal. 

Effect

The MDC control unit receives no engine 
temperature value from the coolant temperature 
sender.
