What is error code 4sns/1/4000000:TB1T-0.000

Running the hardware test, I get the error code 4sns/1/4000000:TB1T-0.000.
Does anyone know what this means?

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.

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.

What does error code: 4SNS/1/40000000: tm0p -61.000 mean?

I just dropped my MacBook Pro "17 i5 500GB 4G RAM (2010 Model) about 3 feet from a chair on to the floor of my house (hard wood flooring), unfortunately.
Everything seems to work well but I went and did a hardware check, but Pressing "D" at startup, I got this error:
4SNS/1/40000000: tm0p -61.000
What does this mean?

Thanks, I will try to take it to the Apple Genius Bar this week.
And I have 3 more questions:
How much will this sensor cost? is it expensive?
Is it a serious issue? Because when I run the hardware test, it only gives me this error in the short test NOT extended test.

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.

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.)

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!

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.

Extreme Fan Speed (Error Code: 4SNS/1/40000000:Tp0P-131.000)

My 20" 2.4GHz Intel Core 2 Duo Aluminum iMac was purchased on 3/21/08 and it was perfect up until about the end of November. Now upon immediate boot up the CPU fan runs up to 3500 rpm for no apparent reason. At first this problem would only happen every now and then, but now it does it every single time. I've tried several things like reseting the PRAM and the SMC and that would work at first, but that doesn't do anything now. I ran the Apple Hardware Test and I got an error code (4SNS/1/40000000:Tp0P-131.000) when the fan was running at 3500 rpm, but when I ran the Apple Hardware Test when the fan was running at normal speed no error code came up. I recently took my iMac to an Apple Store and they looked at it and kept it for about a week and they said they could not find anything wrong with it and told me it was "normal" for the fans to speed up every now and then when it needs to cool down, but why would it need to cool down when I just booted it up and have no applications running? They told me that it could be a logic board problem or fan problem and they ordered the parts, but did not replace anything due to them not being able to find a problem. This problem has become extremely annoying cause the fan is quite loud and I absolutely loved the silence of the iMac when it was brand new. I don't have AppleCare, but my iMac is still under the 1 year warranty and I'm starting to feel that the only way Apple will do anything about this problem is if I purchase AppleCare. So has anyone else encountered this problem and if you have were you able to get it taken care of cause I'm getting extremely tired of this fan noise and I'm in desperate need of a solution.

I gave them the error code when I took it in and they just kind of shrugged it off and days later they called saying they ran several extended tests and were not able to detect anything wrong or reproduce my problem, but I remember the guy at the Genius Bar was able to reproduce the problem.

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.

Solution for error code: 4SNS/1/40000000/IBOR-9.426

My computer recently has been running at its best. I did a diagnostic and gave me an error code 4SNS/1/40000000/IBOR-9.426. I wanted to get an idea what this means and what is the solution?

That indicates an internal sensor failure. You will have to take your MBP to an Apple store genius bar for repairs.

Crash on start up. Ran hardwear test got error code: 4SNS/1/40000000:IC0C-65.828

Have Mac Pro 13" crash on start up. I ran hardwear test got error code: 4SNS/1/40000000:IC0C-65.828
Mac is only 1.5 yrs old and out of warranty. I searched the net and found code= CPU0 problem but don't know if accurate. If CPU problem I guess a new logic board? I am pretty shocked I have a hardwear prob like this. Any ideas?

no one knows exactly what those codes mean except Apple techs. A guide/key explaining those codes has not been made public. While others in here can make vague gueses as to what it may be, you really need to bring your mac to an Apple store or AASP for evaluation.

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.

I did a apple harware test i have an error code 4SNS/1/C0000008: TG)H- -124

i have an error code 4SNS/1/C0000008: TG)H- -124 What does it mean ?

I don't know, but it could be a sensor that controls a fan. There is also a sensor on the rear of the display that could also control one of the fans.

Apple hardware test error 4SNS/1/40000000: TB1T-128.000

I have just bought a used Macbook unibody 2.4, 6GB DDR3, 500GB 7200
And did a apple hardware test which showed the error "4SNS/1/40000000: TB1T-128.000"
What might it mean and how serious it might be?
I tried to google it and found out but not successfully.
Could anyone help with it?
Thank you.

It's a sensor error. We have no access to the "translation" of hardware test diagnostic messages. You'll need to take the computer to an Apple service center.
