Re: 2001 catera engine light P0411
well in my situation i never have this code before, and O2 sensors (before cat.) was replaced due to check engine.
i remember every single time i turn car on after it was seating a while, air pump starts working for about 20-30 second then shuts off and some time working during driving.
but now after i got that p0411 code its like dead, but i did check relay and plug 12v to it and pump work!!!!!. according to manual there is no fuse for it, just relay and its work. i don't understand what else can be wrong!!!!!!! why pump is not turning on!!!???????????!!!!!
