Update, 42000 miles, the light is back. I did the switch-on-off-like-a-maniac to check it, yes, it is P0441 again. No visual sign of damage, unless some piping or hoses are cracked.. Damn!
Hyde........See you Saturday with the FSM and we'll see if we can figure it out. I just threw it in the Jeep....I got a hernia.
