Error 4SNS/1/40000000:TWOP-128.000

Helo. On my MacBook Air first generation with all update made, until few hours ago the wireless was fine. But during a connection I lost signal and the card was no more found. With the Apple Hardware Test (reboot with D) I found the error: 4SNS/1/40000000:TWOP-128.000 but I wasn't able to obtain more info.
Does anyone have more help for my problem?
Many thanks to everybody.
Regards.
Luca

That error code indicates a problem with the main logic board. Try resetting the SMC:
1. If the MacBook Air is on, turn it off.
2. Connect the power adapter to a working power source.
3. Press (left) Shift-Control-Option along with the power button once.
Note: Only use the keys on the left side of the keyboard.
4. Wait 5 seconds and press the power button to start the MacBook Air.
If that doesn't cure the problem, you'll probably have to take/send your Air in for service.
Hope this helps.

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.

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 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 suspect you have hardware problem with a fan sensor. Doing a software install will not help the machine needs to be taken in for service. If you run Apple Hardware Test in Extended Mode it should reveal the error code. If it does not then run AHT an additional 2-3 times to be sure in Extended Mode. Each pass will take about 30-60 minutes.

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.

Error 4SNS/1/40000000/TH00-9.000 Impossible to install OSX

The Mac does not install both Lion and Snow Leopard.
The Apple Hardware Test gaves the error 4SNS/1/40000000/TH00-9.000
I tried to fix HD (but says it is ok), I reset the PRAM, VRAM, and the SMC but it did not works.
Help me please,
Luigi.

I really don't know. Could be as simple as a cable. iMac's hard drives do have a sensor cable attached to the drive from the logic board. But there's really no way of telling. I assume apple gives estimates for repairs.

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!
Kermit

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: 4SNS/1/40000000:TGOD-86.000

I am a full time grad student and desperately need my computer to function properly.
I have a macbook pro that I purchased last year. Its had problems from about 4 months after the purchase until I took it in to be repaired in January 09. An Apple Tech replaced my entire HD (he said some blocks were failing in my HD).
Since then my 1 year "Apple Care" has run out and now my computer does not sleep properly (freezes, does not awake...etc) and it shows the following error when I run a test (no peripherals attached):
4SNS/1/40000000:TGOD-86.000
Some online forums said this has to do with failing temperature sensors and that
a "fix" might entail replacing the motherboard or the HD...what do you think?
WHAT DO YOU THINK?
Thank you very much!
Regards,
Juan

Welcome to Apple Discussions!
Your repair should come with its own warranty--90 days I think. If you are still in the 90 day period, then both the sensor and the new hard drive should be covered. Very likely the plug to the sensor got dislodged during the repair.
If your warranty repair did not fix existing issues, then Apple has a policy of honoring the warranty until these issues are fixed. If they started with the hard drive replacement, then they should be covered by the 90 day warranty.
You could try resetting the SMC to see if this will help with the sleep issue:
http://support.apple.com/kb/HT1411?viewlocale=en_US
Also try a PRAM reset:
http://support.apple.com/kb/HT1379?viewlocale=en_US
I have read many recommendations to wait until the chime has sounded for a third time.
Freezing could also be due to software corruption. Make a good backup of your data, and try an Archive and Install to reinstall the OS.
Also, check the free space on your hard drive to be sure you have 15%-20% free.
There are a lot of steps that can be taken to determine what is going on, but the first one should be to go back to where you had the work done before your 90 day warranty is up.
Good luck!

MBP 13" - 7,1 error: 4sns/1/40000000:tn1d-104.000

My computer fan runs constantly even when just using Firefox and the macbook also runs very hot. I've done a lot of audio recording in the past and the noise is always a problem. Also, last week I installed a couple programs to livestream video and hope I didn't fry something because my CPU was running over 100%.
The worst thing is that yesterday while I was watching a youtube video I began to see a bunch of horizontal white lines going back and forth across the entire screen. It didn't come back after a hard reboot but...
This morning I ran the hardware diagnostic test and it returned the following error message:
4sns/1/40000000:tn1d-104.000
Does anyone know what might be causing this?

The fan in the MBP will run high as a default if the sensor has failed (6200 rpm). Did you tell the technician about the AHT error message? Did he take any corrective action or tell you specifically what options there were to rectify the situation?
Based on your reply, I am concerned that you may have gotten a short shrift.
Ciao.

I recently ran a diagnostics check after my macbook was recieving some problems. I got this error. After a quick google search, I couldn't figure out what it was. Could someone explain what this error means?
Some problems with my computer include:
•Extreme lag
•Overheating
•Excessive Fan usage (6200 rpm from the moment I turn the laptop on)
•Internet randomly turning off

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.

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.

Imac Error Message 4SNS/1/40000000:TH00-9.000

I have an Inter Imac 3.06 I3 and just upgraded the harddrive from a 500gb to a 3tb Western Didgital Cavalier green.
As far as I can see, everything was put back correclty (not much to move when installing anyway) but ever since I put it all back, used time machine to get it back to the way I wanted (of sorts) after about 10-30 mins the Mac fan kicks in. Never did that before. Now this never happened before and the drive runs quiet and you cannot feel it over heating.
I ran the Apple Hardware test and it came up with 4SNS/1/40000000:THOO-9.000
As far as I can see, this and every other code seems to relate to the imac fan switching on when ever it wants.
any ideas on how I can rectify this issue without have to revert back to the old hard drive?
Thanks
G

From 2009 onward iMacs come with HD's that have circuitry for fan sensors integrated into the drives. This means if you installed an off the shelf HD it probably is missing this circuitry therefore causing the fan malfunction. In order to fix the problem correctly you will need to remove and replace the drive currently installed. I would recommend contacting either OWC (www.macales.com) or a local AASP for information about what drives will work in your machine.
