    I published a video on how to troubleshoot and solve your P1443 P1444 P1445 and P0433. Which are codes related to you EVAP system. Specifically the special system used on the 1997 Ford Escort, 1997 Mercury Tracer, 1995-1997 Ford Ranger, and other Mid-nineties Ford vehicles known as the "Evaporative Emissions Purge Flow System." I showed how to do it WITHOUT expensive tools.

    In the past I personally found these codes a little tricky to solve. You often cannot just throw parts at these codes and not have further trouble come back. I cover WHY in the video. Additionally, parts stores have mislabeled the parts.

    The video is a little long, but I keep the rambling to a bare minimum and pack in the information.
    Here is the link:


    I also made a video with more detail exclusively on how the Evaporative Emissions Purge Flow System works. Even pulling information from Ford's Patent and discussing how the electronics function:

    Anyways, I hope this helps out some people solve these very common codes.

    Thank you. A small part of the video got cut off. Note that a bad gas cap can NEVER generate an evap code on the 1997 Ford Escort. Also any leaks between the solenoid and the gas tank/gas cap cannot be detected. However, those leaks will effect the overall function of the evap system. Blockages can be detected.

    Hello, Adamprince2

    I want to thank you again for these videos. I'm the guy who asked you on YouTube about the vaccum measure on the throtte body port. Checked my PC/ED and found it's at least 10 mmHg at part throttle.

    As I don't have a vacuum pump, I had to do a preliminary test and just... ahem... suck on the ENG port and see if it would hold my tongue for 20 seconds.

    The P1443 can get really frustrating to solve. I just sent my second purge solenoid back because it doesn't hold vacuum. Autozone had to give me my money back.

    Carlos85G + Joey, Thank You. I know how frustrating these problems can be. Especially, when your dealing with mislabeled auto store parts, low quality hosing, bad sensors/solenoids, factory defects, poorly calibrated sensors, defective multimeters and scarce information to top it off. At least I can provide some decent information to help guide people through a diagnostic/repair nightmare.
