For $60 I think it would be worth it to run the test and make sure lines arent split/cracked before you start throwing new parts at it

well you can also just buy hose and redo the lines just for safe measures, its very easy to do. its one line that comes in from the passenger side fender and goes to the canister then goes to the purge solenoid then the back of the plenum.

The OEM (Echlin) flow sensor & purge solenoid are available at NAPA. They are exact replacements and sport the Ford logo.

The P1443 DTC refers to whether or not you have flow and how much flow you have from the Charcoal cannister. If the flow sensor doesn't detect flow or enough flow, it will set the MIL. If you replaced the solenoid, unhooked your negative cable from the battery ( for at least 10 min.), hooked it back up and the MIL comes back; then it is most likely a faulty flow sensor.
Do you have a multi-meter or access to one?

P1443, I hate this code only because i hate seeing my check engine light on. This thing came on every time i gave my car a good stomping, the code said it read a fuel pressure increase higher than blah blah blah or lower than blah blah blah.

Long story short I replaced the purge flow sensor, and a few hoses and its been a while since its come back on. Lets hope it stays that way.

Your best bet is to replace any hoses that may look cracked or worn, this is in no way a waste of money because used, cracked, and worn hoses need replacing anyway and they're cheap. Then clear your code and if it comes back on then you can look into replacing sensors.
