Code P0454 2009 Ford Fusion Description

The Evaporative Emission System (EVAP) control system pressure sensor detects pressure in the purge line. The sensor output voltage to the Powertrain Control Module (PCM) increases as pressure increases. The EVAP control system pressure sensor is not used to control the engine system. It is used only for onboard diagnosis. The Diagnostic Trouble Code (DTC) will set when an intermittent voltage from the sensor is sent to the Powertrain Control Module.
