Secondary air injection system leak detected-Bank 1 & 2... 2003 miles on my car and the CEL pops on this morning. VCV bodies are being replaced tomorrow. The tech didn't fully understand what parameters to test for or what conditions would be present to set this code, I can't say that I do either... the flapper could possibly play a role in this..?
View 5 RepliesI got 2001 vw jetta 2.0.. I keep getting check engine light,,when i scan it keep saying P0411 Secondary Air Injection System Incorrect Flow Detected. i replaced new smog air pump, and new egr valve and today i was driving car and i got check engine light, its still same code.

2004 VR6 24v ... I had another thread about my son's car stalling after driving about 20 miles and then running good again after letting it sit for a couple of hours. Anyway I changed the Crank Position Sensor and I have been driving it work and back the last couple of days so I am starting to relax that the CPS fixed that problem. Won't be positively sure for a while as the problem took a while to occur. So far so good.
While coming to work today the car picked up the P0411 code, secondary air injection system incorrect flow. When I changed the CPS sensor i unbolted a module underneath the car by the oil filter to get better access to the CPS. I did not remove it, just unbolted it so I could push it out of the way about and inch.
After putting it all back together and driving it for several trips with no stalling this P0411 comes on. Is that module I moved the Secondary Air Pump and could I have disturbed something. I will check it when I get home. How critical is that code. I read where it works to warm a cold engine. What effect would there be driving with that code?
120K miles - love the car
CEL, skid, VSC trac and VSC off lights on - dealer said the code was p2441 Secondary Air Injection System switch stuck. Dealer said I needed to replace air injection system and that the cel would not go off until it was repaired. They completed the 120K service and when I picked it up, all the warning lights were off. I have driven it a couple of hundred miles since then and still no lights. Does that mean it could have been something else???? I love the car, but I need tires and brakes and now repair charges for a 2005 car with 120K.
I keep throwing a P0411 - Secondary Air Injection System error. My previous pump was seized so I replaced it, and broke a few of the chintzy air hoses in the process. Now, with new pump installed and new air hoses connected, I can go about 5 days before the code comes back on.
So to recap, I have:
Replaced the air pump
Verified the new air pump functions, yepReplaced the air hoses
Verified connection of air hoses at all junctions
Checked the Secondary Air Relay for function
I have not yet checked the solenoid - unsure how to do so.
It all started with a fuel cap loose light (it wasn't) after a day or two the MIL came on and got this code I reset it but I'm sure it'll come back since there's probably a real leak. What can I check myself to find this leak?
View 11 RepliesMy 2006 W12 has been trouble free since taking delivery over a year and a half and 30K miles ago. Just broke 60K total miles over the weekend and the engine light came on. I have pasted the scan below. I cleared the codes and drove about 500 miles before the MIL reappeared. I have read this thread: [URL] ....
My first question is: Is there any harm in continuing to drive it?
I have visually inspected the secondary air injection system hoses and can't find anything glaring (no kinks, leaks, disconnections). I am open to taking the car to the dealership but I have low confidence in their diagnostic capabilities. I am fine with them doing work once we know what is wrong but I want to tell them what to do (replace a bunch of hoses for example). How to proceed?

[Code] ....
Just got the dreaded p2440 code which is the secondary air injection valve failure. Not only do you get several lights on the dash, you also get limp mode with this code.
My GX is a 2011 with 46k, and even though several Toyota vehicles have had their warranty extended to 10yr 150k for this very system, Lexus has done no such thing.
The dealer was very familiar with this issue and knew it wasn't covered under any existing warranty. He said it's "around $2000" to fix because one of the valves is still under the intake manifold.
Even though I hate to "RIG" my GX, I ordered the bypass module from EBAY. It blocks the system off and tricks the ecu into thinking all is well.
For those not familiar, this system runs on cold starts for 30 seconds or so to warm up the cats, it has no other function.
My 97 E350/460ci occasionally sets trouble code 4011. It clears every time I check it with my code reader. Something about insufficient secondary air injection. The dealer ship couldn't duplicate/diagnose the problem. Maybe something with the air injection solenoids.
Otherwise, it runs fine. I did notice on the passenger side of the engine compartment a large black metal filter looking thingie with about a 3/4" outlet that doesn't have any hose on it or seem to go anywhere else. Once in a while when you start it i hear a sort of soft popping noise for a few seconds that I would associate with the air pump.
Also can't get the ABS light to go away. It's out when you start it but as soon as you get going it comes on. I flushed the fluid and replaced the rear sensor to no avail. Also tried to flush out the front tone wheels and sensors.
This is the code i pulled from Vag. Its not the gas cap...

P0456 - EVAP System: Very Small Leak Detected
2004 VW touareg v6 - engine light on - autozone diagnosed as code P0456. Possibly gas cap, so I replaced with aftermarket gas cap from auto zone. Light still on. What can I do or replace to fix problem. I read something about a N60 or N80 valve. Is this something I can buy and replace myself. Most of my mechanical experience is related to working on a 85 CJ7 with an inline 6cyl or Chevy trucks. If the N valve is a easy fix, any instructions and pictures of how to do this.
View 1 RepliesIn the past few weeks I have seen an intermittent "Level Error-Workshop". However every suspension function has worked perfectly, and no height was lost even while sitting at the airport for a week.
How to track down the leak. I can see a tank pressure of about 13 PSI. Is that about right. I did a raise / lower while VCDS was connected and there was a pressure drop to about 11.7 PSI but no level error. What is the correct range of tank pressure settings?

CEL came on after a couple of driving cycles showing code P0456 (evap emission control system very small leak detected)............. car drives fine has good gas mileage.....
View 13 RepliesI own a 98 f-150 5.4 with 70,000 miles. I get a check engine light (code p0455-large leak detected in evaporative emission control system).
Replaced the gas cap with an after market 'stant' ( I believe was the manufacturer) brand. The check engine light went away for 4 days then came on again.
No obvious vacuum line leaks.... Puzzled.
My check engine light went on, and when I scanned my car it gave me the code P1424. I don't know what seems to be the problem?
View 2 Repliesso my girls car is throwing an evap code (P0442) small leak detected. I bought a new oem gas cap and replaced the purge valve solenoid under the hood. that didn't work, CEL still comes on about 100mi after clearing the code.
I have checked the rubber hoses that were attached to the purge valve solenoid when i replaced it and they are fresh, no dry rot or cracks that i can see. The hose on one side goes to a hard line that runs under the car to the back, the hose on the other side of the solenoid runs under the intake to the throttle body. That hose was fine as well. Connections were tight and i even put better clamps on the hose ends that attach to the solenoid. So I have ruled out that portion of the system (under the hood).
I also removed the rear seat to access the fuel pump. All those connections seem nice and tight, I don't smell any strong gas fumes indicating a leak so i don't think the fuel pump gasket is the problem either. Finally, i checked out the hard lines running under the car front to back and I see no apparent or obvious damage. I assume my next step is to pull off the rear passenger wheel well liner and asses the charcoal canister and the LDP connections, correct??
The last thing I will mention is, Idid notice the 2 fuel lines that attach to the fuel regulator are in pretty rough shape, however not leaking any fuel. Are both of these lines actual liquid fuel lines? I am thinking one of them is a vapor return which may be part of the EVAP system. If it's dry-rotted and leaking vapors could that be the culprit??
I recently picked up a 2000 jetta vr6 for a very good price its a glx I have owned a vr6 before and done timing chains myself on it this one is a glx , I am having 5 fault engine codes on my vagcom they are cam position sensor , knock sensor, secondary injection pump, and mass air flow it ran fine 100 miles yesterday this morning the epc came on then went off and ran bad can these codes all be related or do I have to replace each sensor individually..
View 9 RepliesWhere the secondary air injection pump is? I'm getting P1411 & P1423 codes.
View 4 RepliesI have a beautiful 1996 Saab, 900s. Recently the check engine light came on and at Autozone they said the code was for the secondary air injection pump. I took it to a new mechanic, he checked it out and called me to say the pump itself was broken and would cost 1,000 to fix. I said that was a lot, and would think about it, and picked up my car.
Strangest thing- the check engine light is now off! Is this normal? And I just took the car in for the state inspection, it passed! I was under the impression a car without a working secondary air injection pump can't pass emissions. What is going on here??
Finally getting to my header and exhaust install.
I plan on removing the secondary air injection as I have no provision for it. Will this throw a CEL?
Looks like it goes into a rubber hose and comes around to the top of the intake manifold.
What is the best/cleanest way to cap this off?
