Task
Detects the in-tank pressure for leakage testing of the purge system.
Function
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.
The output signal is dependent on the in-tank pressure: -50 mbar approx. 0.5 V, 0 mbar approx. 3 V and +30 mbar approx. 4.5 V.
