B4/3 Fuel tank pressure sensor
B4/7 Fuel pressure sensor

Location
The tank pressure sensor is located above in the fuel filter housing.

Task
The fuel tank pressure sensor detects the pressure inside the fuel tank for testing for leaks in the purge system (leak test).

Function
The fuel tank pressure sensor detects the internal pressure of the fuel tank and issues a corresponding voltage signal to the ME-SFI [ME] control unit (N3/10).
The voltage supply of 5 V is performed by the ME-SFI [ME] control unit.
