2000 Ford Expedition XLT 5.4L MIL Lamp on
Posted to Ford Driveability on 1/11/2006 9 Replies

I replaced the PCM on this vehicle and finally got it to take. I now have a P1639 code that won't clear. What do I need to do to get it cleared? I do have the NGS scan tool, if that is what's needed. Thank You!
