Well, as you can see the title says it all I'm looking around the internet for some answers and it all comes up with secondary air incorrect flow, now this is foreign to me lol, so if any of you gear heads out there what I need to go out and do to fix this problem I would greatly appreciate it.

 

i had this problem for a long time and i have a k&n fpik the problem with mine was that when i initially installed it i had two vacuum hoses in the wrong spot. looking at other fpik installation photos i played around with the hoses until i got it right and reset the ecu and it been 6 months with no check engine light. do you have an intake? if you do then its probably the same hose problem i had.

 

vac line routing and white check valve direction must be exact. Check it.

 

Thank you very much, you guys are awesome.

 

Same thing happened to me when I changed the serpentine belt. I could have sworn I put the hoses back correctly, but I didn't!

 

I also learned the hard way.

After 2 wire tucks and relocating the secondary air reservoir and hoses under the L/F fender, I had used a vacuum hose connector to lengthen one of the vacuum hoses, which resulted in restricting the vacuum thus giving me the dreaded 0411 code after start-ups. After weeks of resetting the ECU and contemplating what was wrong, I decided to pull the fender again and reroute the hose with a new full length one to the IM and 'walla' it worked. NO CODE after start-up.

Lesson learned: Do not piece together any vacuum hose that may cause a restriction. Always use full lengths

 

voilà

 

Spent the whole day today figuring out what's wrong. Nothing apparently, took the little cap off (saw it in another thread, and it worked for him). But did not work for me, gave me the CEL after 15 20 miles.

SO what did I do? Ordered Izzy's airpump simulator

 

I've had this same check engine light but my hoses are in the correct order....any ideas of what else it could be?
