  Charge air temperature sensor, location   GF07.04-P-5038-03AM 
  Charge air temperature sensor, task The charge air temperature sensor detects the charge air temperature and transmits a corresponding signal voltage to the ME-SFI [ME] control unit (N3/10). The boost pressure and charge air temperature are used by the ME-SFI [ME] control unit to calculate the supplied air mass. Moreover, the functioning of the charge air cooling system is monitored through the charge air temperature.  
  Charge air temperature sensor, design The charge air temperature sensor has an NTC resistor and a 2-pin plug connection.
IMPORTANT NTC = egative emperature oefficient
