Hey fellas, I had this code pop up on my '96 T-Bird a couple days ago and my code reader just said "manufacturer control". It's never popped a code since I've owned it and never had that code pop up on the previous '94,'95 and '97 Birds I've owned over the years. Any ideas?
 
P1443 is for a lack of detected evap purge flow. This could be a a busted or sticky purge flow solenoid which doesn't open - it's in the passenger inner fender under the headlight, or it could be a vacuum leak in the lines between the canister and the manifold. Less commonly it's the purge flow sensor.

I'd start by checking for vacuum leaks/replacing the tubing and testing the solenoid before replacing it - easy to do with a couple pieces of wire hooked up to the battery.

That's where I'll start then! It might have had something to do with when I pulled out onto the road the other day and floored it to speed up. It came on shortly after that... lol
 
Go thru All of the lines, they are all falling apart at this point. Go to a parts store and buy 3 feet each of 1/4", 5/16", and 3/8" emissions rated tubing. RA has it too.
Start at the tb; The EGR comes off and connects to a hardline.There are 8 pieces of tubing about 2" long between the tb and the gas tank, Most likely, the evap solenoid is laying in the nose, und a tech article.er the airbox. :) The charcoal filter is bolted in, the solenoid is held to it by a short length of tubing ; I used two sizes to adapt it, it's bigger on one end.
If you fix all of those,the evap will work, and the code not come back.
To clear codes in 10 seconds, pull fuse 15 under the hood, reach thru the window,try to start the car. (car won't.)
Put fuse back in, start your car, codes are clear.
drive it to the store across town. You need to accellerate twice to over 45, use all gears,etc.
Search ford motor-obd-ii-driving-cycle.
If my code is coming back, it will right before I turn into walmart,lol.

If you will take pix and document this for us, Your pix and stuff will go in a tech article
