Failure code:4SNS/1/40000001: TB1T-0.000

This is my first Mac, Its just perfect, i have no problems with it, but when i randomly run the Apple hardware test, it come up with this: Failure code: 4SNS/1/40000001: TB1T-0.000
can somebody help me with that?
Thanks

Welcome to Apple Discussions!
The "SNS" stands for "sensor", and the error code indicates a possible problem with a thermal sensor. Did you run the extended version of the Apple Hardware Test? Sometimes you will get this error if you run the quick version, and it may be something of a false positive. See if you also get it when you run the extended version.
Are your fans idling normally or running all out? If the latter, I would be more inclined to believe a problem with the sensor.
Good luck!

Bluetooth failure - hardware error 4SNS/1/40000001:TB1T-0.000

I was installing updates in my computer and suddenly the bluetooh icon started to fail, I noticed that a red led was on (in the mic input), but after restarting it was off, I tried the hardware test and I got the error 4SNS/1/40000001:TB1T-0.000, so I also tried:
- Reseting PRAM & NVRAM
- Reseting SMC
- Deleting the com file of the bluetooth in the Library folder
But the hardware error is the same, I also noticed that when I test the stereo sound the left speaker volume is very low.
My computer is still with guaranty so I'll request the replace of the bluetooth chip and speakers.
Don't waste your time if you did the hardware test and you receive this error message, none of the soft advices you'll find in this forum will work, just replace.
What I'd like to know if it is better to send the computer or the replace the chip by myself, I saw some youtube videos and it looks very easy, and honestly I don't like how the technical service treats the computers.
Thanks in advance for the advice,

Dear all, after some reboots, and honestly I don´t know which of the previous soft advices was, but my bluetooth is now working.
Just as a extra comment, the mighty mouse bluetooth is the best i ever had, works for Windows Vista better than in OS X. This genius idea of having the right and left button options in one button is very awesome.

AHT error code 4SNS/1/40000001:TB1T-0.00?

Running the long AHT on a Late 2008 (Unibody) MacBook Pro produced error code 4SNS/1/40000001:TB1T-0.00. I gather this is a logic board issue of some kind; does anyone know more about it?

Thanks; do you know what kind of "sensor"? I put the bottom plate back on, zapped the PRAM, and ran the short AHT, which passed. The fans came on, but went back down in a few minutes, so it seems like heat sensors might be okay. I'm going to run some maintenance routines and see what happens.
(A puppy peed on this MBP, and the owner brought it to me because it wouldn't start at all. I opened it up, found some ugly blue-green gunk, cleaned it, reset the SMC, and it started okay. Now I'm trying to figure out how serious the error reported by AHT is.)

What does error code 4sns/1/40000001: IDOR-0.000 mean?

I have a MacBook Pro modWhat does error code 4sns/1/40000001: IDOR-0.000 mean? My video display is partially striated and I ran the self test a few minutes ago.el 10,1 with an NVIDIA Ge ForceGT 650M graphics card with 1GB of VRAM. When I turned on my laptop this morning the right 1/3 of the screen was black with red and multicolored lines, I had to reduce my window view to see the document I was looking at. I rebooted several times and ran the hardware test recommended. The results indicated an error, the code: 4sns/1/40000001: IDOR-0.000. Can anyone decipher the code and tell me what is wrong?
thanks

That error code indicates a DC current anomaly. A visit to an Apple store genius bar is your best option. They should be able to specifically isolate the problem and and advise you of your options.
Ciao.

error message 4SNS/1/40000001 :TB1T-0.000
my macbook also don t reconize any external usb speakers.
internal audio doesen t work as well!!!
someone could help me, thanks a lot

Well, for the last 2 hours, I have been using my MacBook Pro with the battery removed and have had open all the apps that would normally be open; Safari, iTunes, Mail and a couple of others. The fans have stopped blowing at full tilt as they were before, and when I open up a more CPU hungry app like Boxee, the fans go up to over 6000 rpm, but then go back to quiet levels (around 5000 rpm) when it is shut down, whereas before they would either hit 6000 for no apparent reason, or hit 6000 when a CPU hungry app would open, but then never spin back down again.
I think removing the battery has helped but I will take the machine in to an Apple tech tomorrow.

What does AHT error code 4SNS/1/40000000:TB1T-128.000 mean?

My MacBook froze on me last night while running Firefox w/ 4 windows open, each with 6 or more tabs. Seemed partly due to using the instant message ap on Facebook. The machine forze with the beach ball spinning it's heart out. Shut it down, restarted, and got a freeze during start up. Tried again this morning and the machine seemed to run ok for a session, after which I closed the lid without shutting down. After opeing the lid, the machine ran ok, then slow, then froze. I eliminated peripheral problems, eliminated software problems, then ran an Apple Hardware Test.
It produced the code: 4SNS/1/40000000:TB1T-128.00
This code does not show up in Google or this forum. Any idea what it means or where I may find out what it means? It's a late 2008 MacBook, so no warranty whatsoever.
Thanks in advance for any help!

I ran the hardware test on my MacBook unibody and got the same result. Did you ever get an answer as to what this code means? I haven't been able to Google it either.

Error code 4sns/1/40000001:tb1t-0.296?

Ran a diagnostics test on MacBook Pro and got this error message. What is it?

This may be a reference to sensors.
You have to take to take the computer to Apple store for a free diagnosis.
Best.

Failed AHT: 4SNS/1/4000000:TB1T-128.000. What does it mean?

Ran AHT on my MBP to see if there were any hardware issues (the machine seems to be sluggish lately, and frequently has issues when waking from sleep). My plan was to take it in for a checkup before applecare ran out, but unfortunately, my coverage ran out yesterday (the 17th) instead of tomorrow (I was under the impression it expired on the 19th).
Anyways, I ran the apple hardware test, both regular and extended, and they both stopped on the logic board scan returning the error: 4SNS/1/4000000:TB1T-128.000.
First off - can anyone explain what this error means to me? I found an article on CNET that demystifies this somewhat (http://reviews.cnet.com/8301-13727_7-57352461-263/how-to-invoke-and-interpret-th e-apple-hardware-tests/), and from it, I was able to glean that there's something wrong with the temperature sensor on the battery. That said, I can still pull up the temperature on the battery using iStat Menus 3 and it seems to be within norms. This leads me to believe that there's a problem with the logic board. I say this because the logic board has been replaced before during the warranty period, and it would seem that it's a problem component on this model line. (Refurb MBP 15" late 2008 - FB471LL/A)
If this is indeed a logic board issue, what are the chances I can get apple to spring for this repair free of charge considering the circumstances (only one day outside of Apple Care coverage, has been an issue previously)?
Any help the community can offer would be greatly appreciated. Thanks!

For reasons unknown to me the AHT codes are not available to the likes of you and I. Take the MBP in to the genius bar with the code information, and they will know what it means.
As for any replacements of the logic board, all I can say is that I wish you the best. No one this forum has any say in such matters.
Ciao.

Hey! so i was do a AHT on my macbook pro retina and their was a error 4SNS/1/40000001:1DOR-0.000 need help thanks!

Welcome to Apple Support Communities
It looks like you ran Apple Hardware Test without plugging the MacBook to the charger. It's normal to see an error if you run Apple Hardware Test without your Mac plugged.
Plug the MacBook Pro to its charger and run Apple Hardware Test again

MacBook Pro (13-inch, Mid 2010) 4SNS/1/40000001:TN1D--1.000

My MBP recently started freezing (to the point where the mouse wouldn't even move), so I ran Apple Hardware Test and it gave me the error: 4SNS/1/40000001:TN1D--1.000
Various websites in the Mac community say this error inducates a bad temperature sensor on the logic board. However, I have replaced these on several 15" MacBook Pro's, but to my knowledge this simply isn't possible as there are no removable temperature sensors on the 13" MacBook Pro!
I guess my only option is soldering a new one on- luckily, I have a surplus of bad logic board lying around. Does anyone know the name and location of said temperature sensor?

A lot cheaper option that would impress you greatly would be the 8gig of RAM and a 1TB HD upgrade.
Total cost on that upgrade would be around $140 for both the 8gig and 1TB, ..... a Toshiba/Hitachi 1TB 5400RPM 2.5"
as for the SSD, a Samsung 830 256GB,
Crucial m4 256 GB

Hello. Apple hardware test has detected an error. 4SNS/1/40000001:TN1D--1.000

Hello. Apple hardware test has detected an error. 4SNS/1/40000001:TN1D--1.000 Anyone knows what that means ? OS doesn't boot. Maybe it's hard disk error ?

It means your screwed if you're out of warranty.
That error translates to your northbridge temperature sensor is bad- BUT IN MAC "GENIUS" LAND, that means you either need a whole new logic board (a $700 part) or buy a new MacBook. On the non-unibody MacBook pros, you could have came to my store and spend $75 and had a working computer the same day- this is no longer possible on the unibody MacBooks.
WHY, WHY, WHY?
In a bold design move, Apple decided to SOLDER the thermal sensors to the logic board (along with many other components such as the video, graphics and IO), thus rendering these parts NON-SERVICEABLE by us independant technicians. Apple's reasoning is that they can "make their notebooks thinner", but why sacrifice performace for asthetics? Who cares, buy a new MacBook.
WHO NEEDS TEMPERATURE SENSORS?
It doesn't matter if your laptop is running hot or not, when a temperature sensor goes bad on a Mac, it shuts your computer down to prevent further damage. Apple was the first company to implement this "failsafe", now PC motherboard vendors are following suit after watching Apple's stock soar. What this means: Is that you could actually have a perfectly functioning MacBook except for one thing; the little guy who's sole purpose is to report whether it's not the computer is running hot or not has decided to not show up for work, so they closed up shop. If you ask me, it's the equivalent of a restaraunt closing on account of not having a dishwasher- but that's just the opinion of an ex-certified ACMT and what do I know- I'm not a "genius" or anything.

Could anyone tell me this kind of error what does it mean?
Thanks,

Noisy fans, AHT error 4SNS/1/40000001:tgod-1.000

Hello, i run an AHT cause my old imac 24' fans came suddenly noisy. (snow leopard)
(I previously tried reset PRAM..., shut down/wait/unplug..., check apps proc%) ...
AHT returns this error : 4SNS/1/40000001:tgod-1.000 What does that mean? What should i do ?
Thanks for your help !

Means you have a defective sensor. I think it may be for the optical drive. That's what makes the fans run at top speed. Please make a Genius Appointment and take it in for service.
