What needs to be fixed on a 2006 Ford Freestyle when the code says EVAP pressure sensor low?

Try this sight and follow the directions. http://www.myjdmphoenix.com/images/04_xB_Repair_Manual/05%20-%20Diagnostics/SFI%20system/evaporative%20emission%20control%20pressure.pdf

Random misfire could mean you need a tune up. If you are at 100000 miles put in good X.C platinum plugs and a/c Delco wires.. Do a good fuel injection cleaning.

Hope this helps.

you probably have blocked passages in the intake manifold. remove the egr and check the port for a clog. you can scrape most of the carbon out with a pick or screw driver and then use some spray carbon cleaner in there. also check the metal exhaust line to the egr

P0452 Evap.Emission System-Pressure Sensor Low Input

The evaporative emission control system prevents hydrocarbon vapors from escaping from the fuel tank into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Fuel Tank Pressure Sensor (FTPS) is an integral part of the evaporative monitoring system. The PCM monitors the FTPS signal to detect vacuum decay and excess vacuum. The FTPS measures the difference between the air pressure inside the fuel tank and outside air pressure to check the purge control solenoid valve operation and for leak detection in the evaporative emission control system by monitoring pressure and vacuum levels in the fuel tank during the purge control solenoid valve operating cycles.

EVAP fuel tank pressure sensor low output. It sounds like the charcoal -filled canister, it's near the gas tank in a cylinder shape.The canister may have cracks or a hose is leaking around the area and it will give a fault code of PO452. Are you smelling any odors or emission smell from the car?
