P0452 2006 Ford Fusion Code - EVAP Pressure Sensor/Switch Low
Quick Answer
The Powertrain Control Module (PCM) monitors the evaporative emission (EVAP) control system fuel tank pressure (FTP) sensor input signal to the PCM. Common causes include Faulty Fuel Tank Pressure Sensor, Fuel Tank Pressure Sensor Harness is Open or Shorted, Fuel Tank Pressure Sensor Circuit Poor Electrical Connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
