  Charge air temperature sensor position At the charge air distribution pipe (110/1) in the V-angle of the engine below the throttle valve actuator (M16/6).  
  Charge air temperature sensor task Measuring the charge air temperature. The signal (together with the signal of boost pressure) is used for calculating the air mass. In addition, the charge air temperature sensor (B17/8) monitors the operation of the charge air cooling system.  
  Charge air temperature sensor function The function of the charge air temperature sensor (B17/8) is identical to the intake air temperature sensor (B17) in the engine M628. The NTC resistor which is installed in the charge air temperature sensor alters its ohmic resistance depending on the charge air temperature.
