Component description for the boost pressure sensor - GF07.04-P-6051P
ENGINE 642 in MODEL 164.1 /8, 203.0 /2, 209.3 /4, 211.0 /2 /6, 219.3, 221.0 /1, 251.0 /1
ENGINE 642 in MODEL 463
Location
The boost pressure sensor is located at the front right of the engine downstream of the throttle valve actuator (M16/6).
Task
The boost pressure sensor detects the charge air pressure (absolute pressure) downstream of the throttle valve actuator and sends this information to the CDI control unit (N3/9).
Function
The charge air pressure distorts a membrane with piezoelements. The voltage that is thereby generated is used by the CDI control unit to determine the charge air pressure.
