My CEL came on last week. First I thought it was my o2 fix fukin up and the sensor sensing that I got no cat. So I put my cat back on and reset the ECU. Everything seemed fine for a couple days when the CEL came back on. So I got the code pulled for me at Autozone and its P0411 Secondary Air Injection System Incorrect Flow Detected. I would just like to know if anyone has had this problem and how did they go about it. I checked all the hoses, connections, and fuses; everything seems to be in order. Any help would be greatly appreciated.

 

Ahh, this is an easy one. Check your intake. There's more than likely a vacuum hose that has come loose/undone.

 

Did that and eveything looks good. Ill take a look tom again with more daylight this time.

 

I had the same problem a few months ago. For me, it was one of those really small hoses on the piping.

 

Yea those things are small. Ill check it out thanx.

Anyone else??

 

Might be the vaccuum solenoid on the back of the intake. sometimes they go bad from the heat of the motor.

 

yea make sure the vac lines are at the right port off the IM... also check it behind the bumper.. the clip or vac line off the unit could have broken.. i had that happen to mine..
taped the clip on and never had a problem for well over a year

 

Thanx dooooods ill check all that out today after school while im putting my tp back on

Ill keep you guys updated. But it will take acouple days cause after I reset the ECU the CEL dosent come back on for acouple days. So as off now its off but I dont know if what I did fixed it.

 

you need to pick up a obd2 tool man...you can find them so cheap these days on ebay and **** its worth it. i got a mac tools one for less than 150 thats lets me remove the cels and its basically payed for itself

 

Mine came back on after I drove around for 5 minutes after I reset it. (it had come loose again)

 

The CEL is back on. I think I might have figured out what is throwing the code. Theres these two lil ruber lines that connect the metal ones that go right undernieth the fuel rail. Well the top ruber one looks kinda stretched and pinched by the fuel rail. I havent had time to put a longer one on but I will today. Im geussing when it was warmer out the line was more flexible and lil longer, but now sinse its gets below 32 here in philly I think the line is super hard and shrunk a lil. But w/e Ill check it out today and let you guys now.

And yea I need to invest in that tool. It would be so much easier I hate depending on people.

 

How am I supposed to work on my car in this??



Shity cell phone pic but im sure you guys can see what im talking about

Thanx for the invite ill come up and visit someday.

But I like it here Im stuck right in between philly and the burbs.


Anyways *** this snow and all the thats not letting me fix my car. Im going to do it tom morning in school b4 class. I figure the motor will warm up the tiny ruber lines that I have to replace so they come off easy.

 

I changed the lil hose/line like 5 mins ago when I got to school and I reset the ECU. I geuss ill find out if that was a problem in a day or two if the CEL comes back on.

 

We were only supposed to get a dusting of snow down here, but we ended up getting 4 inches. Oh well, the car is still at the body shop anyways.

 

So yea the lil hose thing didnt work I geuss that wasnt the problem. Oh well looks like Im taking everyhtign apart tom and checking it out.

 

good luck

 

No.6 ACG (15 A) check this fuse under the dash.

 

Im about to go do that. And take my fenderliner off to check all the hose conections and ****. hey but check out this pic its shity cause its a cell pic plus im driving but its a bunch of sevens.

 

K so saturday I tore it all apart and looked at evrything changed all the fuses cleaned all the electrical connections. Nothing looked bad, everyhting seems to be fine, everything is connnected, and working. I reset the ECU and the CEL went away. But now its back on. I honestly dont know what the problem is. Can someone plz plz plz help me. I would be more then happy to meet up with anyone if you are anywhere around the philly area or the burbs. Someone plz help.

 

This happened to me in the past. Check the secondary air pump for tree leaves stuck in it. It may decrease the airflow I do know that 2 years in a row after I installed my CTSC, my car throws the same CEL when its cold. On warmer days, it clears itself. So I dont let it bother me, cause I dont drive it much when its cold
