Lexus GX 2010+ :: Codes P2440 And P2442 - Air Injection System Fault
Jan 3, 2016
I have a 2010 GX460 with about 81000 miles on it. I recently got the above codes and after researching it I decided to take apart the air injection valves, and also the motor to see what was going on.
Luckily these parts are very easy to access on our cars. Take the engine cover and front plastic cover off. The two valve are on either side of the cylinder head, and the pump will be on the left hand side, front of the engine bay.
I ordered two new valves, and ended up just cleaning out my pump.
Here are the Part Numbers:
VALVE ASSEMBLY, AIR SWITCHING
2570138100
VALVE ASSEMBLY, AIR SWITCHING
2570238050
This is exactly what happened: [URL] ....
Here is what both of my valves looked like:
Here is what the air pump looked like:

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 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?

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.

First, how can I get the fault codes from ABS system? I cannot find the connector from where to activate it. Looking for a picture where is it located, and how does it look letterike?
Second problem is with starting, occurs sometimes. I just crank the engine, but it doesn't start, when I play with gas pedal, then it will start with 2-3 cylinders, runs really rough for half a minute like this (I hold the gas pedal down, otherwise would die), then gradually gets better until normalizes. Some other time, starts and runs fine. It could happen both with cold or warm engine.

Ok, so I scanned a 2006 Passat 3.6 4mo. I got a fault for the catalyst system, a fault for the AWD controller, and a fault for the Haldex pump. I'm guessing the catalyst code is for the oxygen sensors? What should be my next course of action on the AWD stuff?

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?

My check engine light has came on and I received these error codes
PO441 : Evaporative emissions control system incorrect purge flow.
PO 455 : Evaporative emissions control system pressure leak-large leak.
PO 446 : Evaporative emissions control system vent control circuit fault.
Also only my driver side fan is working, may be separate issue?

I picked up a 2007 GS350 AWD with a little under 60K miles a few weeks ago, I've been absolutely loving the car, but noticed the check engine light/check VSC came on this morning on a cold start; it also sounded a bit rough on idle. I have an Android to bluetooth OBDII scan tool for my other cars so I pulled the codes, and it's showing P0300, P1600, P1700, and P1800.
Searched the forums and nothing comes up for those specific codes. But the first couple of things that came up as culprits for check VSC were the gas cap and brake fluid; went out and bought an OEM gas cap and made sure the brake fluid was topped off this afternoon. I reset the faults and drove the car around, but the lights came back on about 15 miles later. It drives and shifts fine, but I still think it's a bit noisy at idle.
A little background on the car: The previous owner only drove it on weekends and for events here and there, hence the relatively low mileage. The car was sitting in his garage for almost a year before I bought it, he finally got rid of it because he wasn't using it. I grabbed it despite a higher asking price because of the mileage and how clean it looked, but now I'm a bit worried. Is this bad gas? Should I flush all of the fluids? MAF or other sensors? I'm a bit lost.

It showed up yesterday and I looked it up that it's the Secondary Air Injection System Switching valve stuck open. I cleared the code but this morning I heard the pump vacuum noise, which I have never heard before but the code didn't come back on. [URL] .....

What can be done regarding these faults? P0037 and P0057
Description:
Oxygen Sensor Heater Control Circuit Low (Bank 1, Sensor 2)
Oxygen Sensor Heater Control Circuit Low (Bank 2, Sensor 2)
The catalytic converters have been removed but the fault was present before that anyway. All I want is the VSC function to work again and the lights to go off. I have heard you can put dummy sensors in.

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..?

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.

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?

Bought a used Prius 2010 last december, Now the hybrid system is shut down and the assumption is that the hybrid battery is the culprit. No codes has been read out of the system but the car has passed 330 000 km so I guess that's very plausible. Have found a used battery from a 2009 prius who the local Toyota service facility says is compatible.

Sunday I received the dreaded DEF system fault message on my 2012 CC SRW SB FX4 with 7800 miles on it. Warned me that speed will be reduced to 50 MPH in 50 miles. I have a CTS Insight, so I checked for DTC's. First one was P2200 - NOx sensor circuit (Bank 1, Sensor 1), the second one was P204F - Reductant system performance (Bank 1).
After 50 miles it warned me that speed would be reduced to 50 MPH on next restart. Sure enough, Monday morning speed was limited to 50. I took it to the dealer, but I should have left it running. When the service guy started it, the fault had cleared and it no longer showed the P2200 NOx sensor code, although the P204f code was still there.
My question is, why in the world would Ford make it so that the code is cleared if the fault goes away, especially after putting you through the 50 MPH limit scenario?
Dealer did a reflash and said its OK now, but I'm not so sure. My trucks build date is 10/6/11. I read TSB 11-11-13 which states the NOx sensor module should be replaced for P2200 on trucks built before 10/11/11. Is that only for a persistent P2200?
