Fig 1: Identifying Fuel Filter With Fuel Pressure Regulator And Fuel Tank Pressure Sensor

The fuel tank pressure sensor is located above in the fuel filter with the fuel pressure regulator.

Fig 2: Identifying Fuel Tank Pressure Sensor - Models 203, 209

The fuel tank pressure sensor is located above in the seal for the left fuel tank chamber.

Fig 3: Identifying Fuel Tank Pressure Sensor - Models 215, 220

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

Task

The 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 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.
