Model 171
55/2 Fuel filter with fuel pressure regulator
B4/3 [1][2]Fuel tank pressure sensor

The [1][2]fuel tank pressure sensor is located above in the fuel filter with the fuel pressure regulator.





Models 203, 209
B4/3 [1][2]Fuel tank pressure sensor

The [1][2]fuel tank pressure sensor is located above in the seal for the left fuel tank chamber.





Models 215, 220
B4/3 [1][2]Fuel tank pressure sensor

The [1][2]fuel tank pressure sensor is located at the top in the fuel level sensor (B4).

Task
The [1][2]fuel tank pressure sensor detects the internal pressure of the fuel tank for the purposes of checking the leaktightness (leak test) of the fuel system.

Function
The [1][2]fuel tank pressure sensor detects the internal pressure of the fuel tank and sends an appropriate voltage signal to the ME control unit (N3/10).
The voltage supply of 5 V is performed by the ME control unit.

The measuring range extends from approx. - 50 mbar up to approx. + 30 mbar.
