EVAP Purge Pressure Sensor (7/407) [2021-2022]: Description

The EVAP purge pressure sensor is connected to the purge circuit after the EVAP purge pump EPP and before the EVAP purge valve. The sensor measures the pressure in the EVAP purge circuit and in the fuel tank (when EPP is not actuated) to determine the need for actuation of the EPP.
