I failed the emissions testing because of my DPFE (or emissions feedback pressure sensor). I replaced it, unhooked the battery to reset the " check engine light". But the next day when I went for testing I was told my PCM had not finish cycling, and was incomplete. Come back and test another day. How long after the battery pull does it take to reset the PCM? I dont have a scan tool to reset it so my only option was this method.
