So the original P/N is 226806N211 or replacement P/N is 226806N21A.

​Mine died this afternoon, who wants to split freight with me & get a couple?

22680-6N21A(current) and 22680-6N211 is the superseded part.

I bought a wrx one. Should be here today.. if it ficks out ill grab one with you.

So the original P/N is 226806N211 or replacement P/N is 226806N21A.

im glad I'm not the only one who has trouble with afm bloody things, fingers crossed all good and 14 months has passed:)

Hey guys, had to post up a statement of love for these forums. This all happened to me a few weeks ago while giving a bit of a squirt.. basically stalled at 80 and i was stuck on the side of the road. jumped onto SAU on the phone.. search.. wallah I read about this common AFM issue.. unplugged it and it kicked over first go! limped my ass home and ordered a new one using the model codes from this thread and I was back on the road in 4 days (including weekend). Any other car with a poor aftermarket following would have no forum support, and would be stuck waiting for NRMA or a tow truck.

In case anyones interested in another source for this AFM.. try www.CyberspaceAutoParts.com.au

I got the sensor for $220 + delivery.. much better than $307 and 2 weeks from Nissan!

Cheers

22680-6N21A is the one to get. Don't buy a copy one, They are actually designed differently, weigh half as much, don't last and will have your car running B grade.

Speaking from experience..

Speaking from my experience; a brand new Nissan one at $270 lasted almost 3 weeks. I'm not the only one to have the same experience. No warranty, and they laugh all the way to the bank.

I bought a generic ebay WRX STi AFM, and it lasted about 3 years. Bought one of Scotty's Chinese ones; still going after a year.

I'd buy 5 copies before I even considered buying another one from Nissan.

Fit an Emanage, then you can probably go a Z32 or VQ35 afm and never have an issue again. :)

I'd be willing to bet the Maxi-Rom could probably be scaled to cope with the change as well.

Apparently not when I asked him, as it's just a basic AFM signal bender. If it had injector and timing control it would I suspect.

so did my first afm after owning for year and a half, luckly had one of scottys sitting in the glovebox waiting for the day it expires. so thought i'd get another (just in case),can anyone tell me is there a difference between 22680-ad21a afm and a 22680-6n21a afm, I have both here and they look exactly the same.

Ok well all differing experiences. My Chinese on lasted 4 days. It was designed totally different than the jap ones weigh half as much and give a different curve which caused idle issues and terrible fuel consumption.

It's possible there are 'better' Chinese versions as some have a green seal and others a black. My failed chinese seal was green. The Nissan sensor seal is black similar to so other Chinese copies I've seen on aliexpress.

Something tells me the Oring color doesn't have much to do with the quality. :P

When you have blown 7 or more Nissan ones at $330 each (like some of my customers), some only lasting an hour or two, you will be looking at other avenues for sure. Took me a fair while to find a decent supplier in China, but they were an exact copy, if not made in the same factory.

Check the WRX forums, the early ones ran the same AFM, they may have a better idea of which ones work.

I was eluding to the O'ring colour denoting the sensor style/batch/brand to help identify/source the higher quality.

Not sure what point your making if your buying the same sensor from China that Nissan use...cheaper sure but doesn't prove or increase reliability. From what I've found on my last two M35s is failure usually increases with pod filters and power ducts. May be more pertinent to relate the failures to vibration, FOD and moisture

I've killed at least 3 OEM Nissan ones, I don't have a pod filter or power duct. They've failed in dry conditions and in wet.. no rhyme or reason. Scottys has held strong for over 12 months now I think? Touch wood.

There is a always a logical explanation. It just has to be proven. I might dissect my blown sensor.

I'm sure there is as many blown Chinese as Nissan sensors. I would also expect some 'nissan' sensors are reproduced Chinese, box and all

What I can confirm is the Nissan sensor I bought for $160 was very very different weight and hot wire design to the Chinese version that I had. Mapping afm voltage and response also was different. Different curve and smoother response. If you have an aftermarket ecu you can mask a different curve.

The big problem we have on the forum is talking apples and apples. There is a chance the sensor I have now is the same that Scotty had previously. post-49288-14422990779322_thumb.jpg

This is the part that was different in the sensor that failed. It had a component in the air stream rather than a flat metal film like this one post-49288-1442299253898_thumb.jpg

This is the one that failed after 3hours use. The IAT thermistor was also double the size of the current Nissan one which would elude to later technology of the Nissan replacement

Another interesting tid bit. If you block off your factory BOV you will induce idle and response issues , low throttle fuel Economy increases/reduction in power.

Why?

The BOV is designed to be open at idle and part throttle which enables the air to bypass the inter cooler traveling from the AFM to the engine via the shortest path. This means that there is a reduction in delay between when you activate the accelerator and when the ecu can inject more air to act on it. Acceleration enrichment can be adjusted to compensate if you have the capability however there is no substitute for a short inlet track. Nissan designed it this way to give the best of both worlds.

Air will naturally take the path of least resistance meaning there will be less vac in your intercooler and piping also giving better transitional response. People have theorized blocking the BOV will increase response but in actual practice this is not the case. The other advantage for our gearboxes is that part throttle will net more control meaning power will be closer to what the TCU is expecting. In racing terms having a accelerator pedal that is linear will away be faster around a track. A blocked BOV will remove most of this linearity give only a small difference from 50% throttle onwards.

I'm no auto sparky but is the wire the AFM susceptible to contamination from oil etc? If so part of it may come down to how it's being handled, i.e are people touching the wire during installation and leaving skin oil on it?

The wire isn't the issue, the afm has an ecu inside it which fails. Could be low input voltage causing it, but I have seen a brand new Nissan afm blow the first time the car was booted, so it definitely isn't dirt or oil causing that fault. The hotwire isnt able to be touched in these really.

The original superseded OEM part number is the one to get, they last many years, it's the new Nissan part number that fails constantly. If only there was a batch of old stock laying around. Until then we are stuck trialling aftermarket afms till we find another good source.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
