TrailBlazer :: 2008 - Secondary AIR System Switching Valve A Stuck Open (P2440 Code)

I have a P2440 code from warning light- Secondary AIR System Switching Valve A' Stuck Open. This started to appear when I took it into the dealer for other issue with transfer case whining when in 4x4. Can this code be associated with something the mechanic did , would they remove any sensors or wires, that may not have put back. Not happy. Are these trucks know for this code? Estimate cost?

Ford 7.3L Power Stroke (1999-2003) :: Fuel Filter Bowl Drain Valve Replaced - Emission System Warning Light

I just changed the drain valve on the fuel filter bowl. All went well and no more leak, but now I am getting an "emission system" warning light.

After I replaced the valve, I filled the fuel bowl with diesel fuel. Was there any other priming that needed to be done (if any)? What the emission system warning light may mean?

2002 F250 7.3L 4x4.

Lexus GX 2010+ :: Secondary Air Injection Valve Failure - Code P2440

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.

Phaeton :: Secondary Air Injection System Fault Codes

My 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?

Golf V R32 :: Code P1414 And P1424 / Secondary Air Injection System Leak Detected

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..?

Golf IV / Jetta IV :: 2003 1.8 Turbo Throwing P0411 - Secondary Air Injection System Error

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.

Lexus GX 2004-09 :: 2005 - Code P2441 - Secondary Air Injection System Switch Stuck

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.

Golf IV / Jetta IV :: 2004 - P0411 Code / Secondary Air Injection System Incorrect Flow

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?

Ford 6.7L Power Stroke Diesel :: Secondary Cooling System Leak / Dripping From Center Of Engine Bay

Turns out I've lost nearly all of the coolant from my secondary cooling system and am trying to diagnose the problem.

Things I noticed:

-All of the hoses appear to be in good condition.
-Coolant is dripping from the center of the engine bay.
-After inspecting the turbo area, it appears the valley below the turbo is wet.

The intake manifold is still on the truck, so I haven't been able to get a better look. Is there anything else near the area I am describing that has coolant? My guess is the turbo water inlet?

Perhaps this : Coolant leak on the 6.7 Powerstroke diesel - YouTube...

Prius (2004-09) :: PCV Valve Needs To Be Replaced Due To Dirt

I had the PCV valve replaced around 60K, then at the next service they wanted to do it again (not reading the records that they had already done it). Then at 80K they wanted to do it again, I declined. Today it was in for 85K service and they said "the PCV valve is dirty and needs to be replaced." The advisor told me after the initial replacement at 60K the interval is 20-25K miles.

Passat (B5) :: Secondary Air Pump Won't Working Properly

I have had an engine code for some time claiming my auxiliary air pump is not working properly. My indy saw no obvious problem, but it could just be shot. He suggested I take it to the dealer. But from my understanding, that pump only works to achieve cleaner combustion when the engine is cold right after a start. I am tempted to continue ignoring it. Would I be making a mistake? I haven't noticed any power or mpg reduction.

I guess I can always take my car in for the under the hood seal recall and have them do a diagnostics too.

Passat (B5) :: 2004 - Secondary Air Pump Hose Broken?

Ok so I accidentally broke the hose that connects the secondary air pump to the stock intake box and been looking around for a replacement. I have looked around and searched and searched and the only one I found is this one: [URL] .....

Will this work for a 2004 1.8T? I know it says that its for the 2000-01 but it looks exactly like the one that goes on mine. Haven't checked the dealer to see how much they want for it but it will most likely be an arm and a leg.
