When you say killed - has the element broken? Have you tried cleaning it - resoldering the joints -= checking the wires to the plug? Have you replaced it with other second hand ones or a new one?

they were replaced with genuine nissan air flow and its happened again.

thanks

Electrical contact cleaner will clean the element of the AFM.

How has it been determined that you have killed the AFM?

the last two were while my wife drove it, and the car would cut out our mechanic said it would be the afm, pull the plug out and take it to him.

then on the way back from the airport xmas night the car was just on boost i went to kick back to change lanes then it did the same thing my wife said.

any you guys have had a z32 afm im told there better ?:huh:

The Z32 has different resolution but is not better.

I still don't understand how you have "killed" the afm. Sure they can get dirty, sure they can have dry soldered joints, sure you can have a wiring issue at the plug but having them fail outright is a bit of a long shot on a relatively new car. You need to find the actual cause.

I have repaired three afm's with dry solder (but much older units that you are using) and have always given the elements a tickle with contact cleaner as a part of routine maintenance.

Ours cant be repaired Wolverine, as far as I know. I pulled one apart and found surface mount processors etc inside them but no dry solder joints. They just seem to die for no reason, although touch wood I havent blown one yet. Are you sure they were genuine Rudi?

To run a z32 you would need to tune your car with an Emanage Ultimate or a Fcon Vpro and modify the wiring and piping to fit it. Did your mechanic explain to you that they cant just be swapped?

The board is potted with some sort of gel, even water wouldnt damage it I would have thought. Perhaps the supply voltage is a little too high? No idea really.

There are a few different types though, perhaps the older ones had issues and were replaced by better ones?

I would try the error codes to make sure, there are many reasons for them to go into limp mode like the brake wire cut mod and throttle motor issues... Perhaps try resetting the ecu properly first?

Yep.

Original part number was 22680-6N211 for the sensor itself which was used on 02-03 Elgrande (VQ35de), all M35's, 01-03 P12 Primera, 01-04 V35's (NOT VQ35de) and 03-06 VQ30det powered F50 Cima's.

This was changed to 22680-6N21A in Dec 2006 which was only used on the F50 Cima VQ30det thereafter.

Interestingly, the sensor used for just about all other Nissan's (including T30 Xtrail, J31 Maxima, Z33 350z, VQ35de powered V35's, V36 Skyline and PM35 Stagea) is 22680-7S000.

6N211 is the number that comes up for the sensor if you go through FAST.

There is a second number to left on the part numbers table which is the updated part number (so 6N21A in this instance).

I don't have a screen shot as I am on the wrong computer, but most Nissan dealerships state the default part number and their system automatically updates the part number for the order.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻

      Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”

      Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2

      By GTSBoy · Posted

      Yes it is ATF. I quote @Duncan "it takes a good synthentic auto trans fluid like Castrol Transmax Z" It's not a diff. It's a transfer case. Totally different thing. Yes, fluid will come out the sender hole. No you do not really need to drain it. Just pull the old, quickly poke the new, clean up and top up. But realistically, you should probably take the opportunity to change it anyway.
