    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 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 filed 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.
