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.

Hi, what does the Error Code 4sns/1/40000000:IDOR-6.188 mean?

hi to everyone
A friend of mine has a Mac Book pro. Several days ago it wouldn't start up any more. It just goes on, then clicks and goes off. The only possibility was to press and hold the Power Button. After this procedure the MacBook booted up but was very slow. The cursor hangs etc.
I was able to do an extended diagnostic test and got the following error:
4sns/1/40000000:IDOR-6.188
I found some messages regarding hdd via google but the hadn't any value for me.
Best regards,

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.

What type of sensor is 4SNS / 1 / 40000000: TGOH- 128.000

Hello all,
this is my very first post. At the moment the CPU fan in my iMac (2008, 2.8GHz C2D, Nvidia 8800) is running at full speed. Apple hardware test is returning an error code:
4SNS / 1 / 40000000: TGOH- 128.000
I checked this forum and it seems to be a problem with a temperature sensor. So my question is:
What sensor is this exactly as there are several in the machine (CPU, GPU, ambient, ODD etc.) ? Is TGOH referring to the GPU sensor?
What is the meaning of TGOH?
What is the meaning of the numbers (40000000 and 128.000) ?
Just a brief explanation: The graphic card in my produced serious faults on the LCD (dots, blinking areas, half the screen orange etc.). I disassambled the iMac, had the graphic card in the oven (200°C for 10min) and replaced the termal paste. After building it all together, the graphic card now works again (no kidding ). But now the fan is running full speed, and I cannot find the fault.
Very much appreciate your feedback.
Thanks and greetings from switzerland
Andreas

Thanks for the tips. Actually I already tried reseting the SMC / PRAM. I was just wondering that AHT is showing a HW error in one of the sensors.
Anyway, I will take the iMac apart and check all connections. Maybe I missed something. I will post when I find the error.
BTW. Yes I placed the entire graphic card board (without the heatpipe) in the oven. I`ve done that before with the entire logicboard of a MBP (with all the connectors etc.). It had a black screen of death, but works again until today. In my case it was a question of having several CHF worth of nice paperweight or giving it a try
But with my iMac i guess the problem really was that the thermal compount was not evenly spread on the GPU. When I removed the heatsink , there were blank spots on the GPU. So I guess the GPU had heat spots. "Baking" it was just a additional precausion.
I just wonder that many NVidia 8x00 seem to produce errors/faults in the Macs.

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.

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?

Welcome to Apple Support Communities.

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.

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.

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.)

AHT Error 4SNS/1/40000000:Te2S-128.000

Hi,
I just ran the Apple Hardware Test on my Mac Pro (desktop) 4,1 with OS Snow Leopard.. and I had an error code which I can't find anywhere online on what error is it referring to. Do anyone know what is this error? How do I fix it?
AHT Error code 4SNS/1/40000000:Te2S-128.000
What does it mean? And how can I fix the error?

Only Apple really knows. Sensor for some type.
What are you using to monitor thermal sensors and the rest of the system?
Download Temperature Montor
Schedule or take it in for a free checkup.
You can google to find the Apple Service Diagnostic CD.
Your Mac is 4 yrs old so likely out of AppleCare?
I could only find notebooks and they wree not that particular sensor code.

I am getting error 4SNS/1/40000000: TG0H-128.000 ? what does this mean.

HI there,
I ran apple hardware test through snow leopard OS disk 2, i got this error 4SNS/1/40000000: TG0H-128.000 , My fans are continously running at 5700 rpm even i am doing nothing. I have booked an appointment with genius bar on monday 6 may. are they expensive to repair or should i find a local apple technician ? is there any other method to fix it.

Your computer has to start from the Windows disc but it's not doing this. After creating the volume, make sure that the Windows disc is inserted, and turn on your Mac holding the Option (Alt) key, so you will see all bootable partitions. Choose the "Windows" option with a DVD, so the Windows installer will start and you must follow its steps.
If you need help installing Windows, follow the steps of this how-to > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.8.pdf

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.
Ciao.

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.

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.

To what does G4 error code post16/4609 refer?

to what does G4 error code post16/4609 refer?
G4 MDD 1.42 PPC passes all hardware tests but gives post16/4609 error at start up.
What does it mean?
What is the resolution?

I don't get any unhappy beeps.
I get the chime. If I am not patient restarting I get high speed fan - I shut off be patience restart and get chime and search for drive then circle slash. hardware test gives me the master post 16 / 4609. - suggesting a bad drive according to other apple pundits. However, I have put two new 250GB WD drives in and still get a mass storage error. My G4 Mdd 1.42 supports drives 128GB+. I've replaced IDE cables and have master drive with out a jumper and have tried slave at CS and 3/4 slave setting all with the same result.
Target boot got me to the "firewire drive" showed me one unformatted 250GB drive and I used disc utility to partition it according the PPC settings. Still same error.
What gives?
