Secondary Air Pump Failure:
What does the system do exactly? To help combat unwanted hydrocarbon emissions, air is injected post combustion for a predetermined amount of time after the engine is started.
The system is only operational for a small amount of time post start (the amount of time varies depending on engine temperature, but is typically around 30-60 seconds), and inactive thereafter. It has no effect on engine performance or fuel efficiency it is solely there for emissions control.

The system consists primarily of an air pump assembly, two air valves and a crossover pipe. There are several variations on the same fault. Either the pumps themselves fail, or one or both of the air valves seize open or closed.

This triggers an engine fault condition and the ECU will show a “Check Engine Light” on the dash. The cruise control system will also cease to operate (and where fitted, the light on the dash switch flashes). The codes can be checked with a generic scan tool.
One or more of the following Fault Codes will be recorded in memory as Current, Historic or both:
- P0410 Secondary Air System Malfunction
- P0411 Secondary Air Pump Flow Abnormal
- P0413 Secondary Air Combi Valve Relay Circuit 1 (Low)
- P0414 Secondary Air Combi Valve Relay Circuit 1 (High)
- P0416 Secondary Air Combi Valve Relay Circuit 2 (Low)
- P0417 Secondary Air Combi Valve Relay Circuit 2 (High)
- P0418 Secondary Air Pump Relay (Low)
- P1410 Secondary Air Combi Valve Open Seized
- P1418 Secondary Air Pump Relay (High)
- P2431 Secondary Air Pressure Sensor Property
- P2432 Secondary Air Pressure Sensor (Low)
- P2433 Secondary Air Pressure Sensor (High)
- P2440 Secondary Air System Open Seized (Bank 1)
- P2441 Secondary Air System Closed Seized (Bank 1)
- P2442 Secondary Air System Open Seized (Bank 2)
- P2443 Secondary Air System Closed Seized (Bank 2)
- P2444 Secondary Air Pump On Malfunction

Solution's:
To fix the whole system i have heard prices from $2100-4000 depending on where you go.
The system can’t be removed from the car easily without
triggering more faults either (the Atmospheric pressure
sensor, used by the engine management system for
ongoing day to day engine related calculations, is fitted
within the primary air valve assembly).
Fortunately there is another solution which is both CHEAPER and gives you the option of added
performance as a bonus!

Step 1: Buy/Install Block off plates.
Google. >>>>>>>Subaru WRX / STI Air Pump Delete - Block-Off Plate Set w/ gaskets<<<<<<<<<<<
You can buy from them Ebay..etc
Price: Around $50.

I used these guys to install them:
http://www.boxerservice.com.au/ Based in Brisbane, but find a mechanic close you. Subaru Dealership will not do it, they will sell you something else.
Install:$400

Or

DIY: (Thanks bigBADbenny)

Welsh plug option
SG Foz iuses 1 x 26 or 28mm welsh plug.
The welsh plug size for SG Foz is 26 or 28mm.

Price: $ a few dollars at Repco


Step 2: Get a Tune.

The Engine fault condition and the ECU will still show a “Check Engine Light” on the dash, after the install of the Block off Plates,The fault codes need to be removed from your ECU.
I used:
Throttle Happy,
https://www.facebook.com/Throttle.Happy.Tuning

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Or

Get yourself a Tactrix openport 2.0 or borrow one to remove codes.

The Basic procedure to tune is as follows:
1. Read the ROM from the car's ECU with EcuFlash.
2. Open the ROM file in RomRaider (File->Open Image) or EcuFlash (File->Open ROM) to tune. Note: After reading a ROM, EcuFlash will attempt to open the ROM for tuning if it is supported by the ECU definitions. Both RomRaider and EcuFlash are ROM editors, so which one you use for tuning is a matter of preference. However, only EcuFlash can read/flash the ECU and only RomRaider can data log, between the two.
3. Turn off the Secondary air pump codes.(RomRaider: File->Save, EcuFlash: File->Save ROM or Save ROM as)
4. Flash the new ROM file (or modified ROM file) to the car's ECU with EcuFlash to apply your changes. Your changes are now permanent until the next flash even if power is removed from the ECU or the ECU is removed from the car.


But do your Research, and find the Tuner/Dyno that suits your needs.

Hope this Helps People New to this. :)
I myself wished i knew this info earlier.

If your in the Bundaberg/Wide bay Burnett region, send me an inbox, i have a Tactrix Cable. Done a few local cars.


If your in Melbourne, send Sharpie a pm.


Here is a Video from MRT Explaining the issue on a MY 08 Wrx Sti motor.

Hi guys, brand spanking new here!

So with this method bigBADbenny I'm guessing you still need to deal with the error codes? My pump has been making the whirring noise on startup for a month or so now and I'm not too keen on letting Subaru here in Adelaide have a crack at it (not the best experiences with them!). I don't have any error codes as yet but assume they'll show up eventually. I think my first attempt will be a removal and clean out of the pump but if that doesn't help I'll be attempting one of these options!

I fit a set of blanking plates at least once a week supplied by adam at Tuspeed here in Melb. I remove valves and switched off codes. Caps, plugs bottle tops etc sounds dodgy. Do yourself a favour, get the correct parts. There can be a lot of pressure behind those plates.

There is no need to fit blanking plates if both valves are stuck shut. I did my mod in 2011 and have helped many people since then to carry out the mod. In all cases the valves were stuck shut so removing the fuses works just the same as blanking plates. In normal running the valves are shut anyway so it is no different from the OE setup.

why wait and see if they free themselves up? ive seen 90% cases of burnt pumps and piping. do it right fit plates.

How could they free themselves up. They are spring loaded shut and if the fuses are removed there is no power going to them they can't open.
