M35 "problem"

[donutdavid]

Hi boys,

Hope someone can shed some light to what happen tonight.

Driving home tonight and at the lights had a bit of a squirt so I could jump in merging lane and all of a sudden revs cutting down and engine light on???

Pulled over quickly turned the car off and after few minutes started again with same thing not going over 2K revsmwith engine light on?

Lucky only 500 meters from home drove very slow. I"m now one very concerned Stagea owner.

Any input or where should I start looking is much appreciated.

Thanks

Dave

Sounds like limp mode. Most likely culprit is AFM.

[Mr 20Valve]

Cutting out & engine light sounds like AFM failure, but it'll normally only let you drive in limp mode (under 2k rpm) when the AFM has been disconnected...

[Daleo]

As others have said, definitely AFM.

Mine died exactly the same way as this also.

[donutdavid]

So when you said died no cleaning will help? Also where to get new one as I would imagine second hand would be a waste of money?

After I replace it how do I get the engine light not to be on or will it clear itself?

Thanks everyone for posting reply!

Cheers

Dave

There was an RB26 AFM fix in the DIY section - basically some of the soldered joints go dry, so you just reheat the solder to make it "take" again. You pop a cap off the compartment where the plug is, and check the pins that run from the plug to the PCB. You should be able to see dry solder joints with magnifying glass, or just re-do all of them anyway. No idea if the VQ AFMs are similar, and of course it could be some other problem.

VQ ones aren't similar and can't be repaired. It seems the processor on the board inside the afm stuffs up, it will require replacement.

The main issue is the original part has been superseded, and the new AFM Nissan supply doesn't seem to last long. Your original one has lasted 13 odd years, these are lasting 4 months if you are lucky. Nissan don't want to warrant them either, and at a cost of $350 each... My suggestion it to try and find a second hand one for now until I sort out an aftermarket alternative for us to use, at 1/4 the price, then keep it in your glove box.

Our original Nissan p/n is 22680-6N211 and the new Nissan p/n is 22680-6N21A.

Regarding our chat the other day Scotty, apologies for not sending the link.

Here is the one that I purchased; Part number on my unit is exactly the same as the one pictured.

http://www.ebay.com.au/itm/290794600600

As Scotty says, I had a brand new, OEM replacement (new P/N) fail in less than 3 weeks. Hit the key one morning, pop; dead.

Super pissed of would be an understatement.

The ebay replacement is working fine; and arrived very quickly. Has been in for a bit over 3 months according to my records.

[Commsman]

Hey Scotty, I was thinking of sending one to my contacts in China to see if they could get it manufactured for a couple of dollars. Would need to buy a few thousand, but if everyone bought 5 or 6 they get used up pretty quickly. It wouldn't matter if they lasted 6-12 months either, if they were that cheap (change with the oil, lol)

However, the risk is they could be as bad as the Nissan ones & then we'd all be annoyed, even if they only cost 5 bucks.

Hey Dale, keep us posted on your experience with the Ebay one. Maybe we could do a deal with that guy for a bulk order?

[Commsman]

Contacted Ebayer to ask for bulk buy pricing, just in case he wants to unload 20 or 30 real cheap.

[scotty nm35]

That is the path I was going down Leon, but I wanted to check the quality and test the airflow map. As Dale is running a Chinese one I assume they work well, as long as they are all coming out of the same factory... And I bet that's the same factory Nissan buy from.

[donutdavid]

Had look on e-bay and could not find any for m35? What search do you use?

[richzx]

Click the link that Dale provided, the Subaru one is the same. $99.

[donutdavid]

No luck with second hand unit so it's either nissan for $318 ex Melbourne or e-bay for $99 or I can get just the sensor from Amayama for 106 bucks?

The question is which one will last the longest??? or will the sensor be enough or do I need the whole unit?

Anyone.....

just the sensor, I've gone thru 4 of them, once done keep it clean. Touch would. Also what filter do you have I've had k&n and was nothing but trouble, paper is the best:)

[scotty nm35]

The sensor is all you need to replace, the tube is just a plastic tube.

The Amayama one 'should' come with a 12 month warranty. Best to speak to them about it before purchase. They are known to last anything from 1 second to 4-6 months. Like I said, I wouldn't be buying one.

The second hand one can come from many different cars, eg Maxima, Xtrail, Pulsar, if you google search the part number you will soon realise they are all similar just with different numbers. Even VW and Merc ones look the same with a different plug. How long it lasts is anyone's guess.

I would just buy the ebay one in the link provided for now and try it out. There are a few guys running them without issue, I just wanted to check how accurate the air temp sensor was to ascertain the quality first. I will probably place a large order directly from China to bring the costs down for us all, and allowing us to afford a spare for the glovebox.

I've got "blitz" panel i the air box but I'll take into account as I have paper one as well

You guys getting early failure on new AFMs should talk to Fair Trading or the equivalent in your state. In NSW Nissan cant get away with saying there's no warrantee since its mandatory under the law to supply goods of "merchantable" quality.

I'd imagine they're going down the "part is being damaged by a fault on the vehicle" if the one on the car fails, then the replacement fails, they'd be arguing that an issue on the car is making the component fail.
