I have some problems with my Mac Book Pro 7.1,
It freezes after starts up or while functioning and I have to force the shut down.
I run the Hardware test and it reports the following error 4SNS/1/40000001:TN1D--1.000.
Could anyone tell me this kind of error what does it mean?
Thanks,

Apple Hardware Test error 4SNS/1/40000001:ID0R-0.000 on Retina MBP

Getting the above error on my 3-day old retina MBP with 16gb RAM and 768GB flash storage. I had loaded Chrome, Firefox, VMWare Fusion, Office 2011, and all the Apple updates as of 7/3/12.
My issue may be related to similar issues I've seen on these boards, relating to sleep or wakeup causing the intermittent crash. Machine has also crashed (kernel panic) 2 times. Genius Bar employee downplayed the AHT altogether, saying it's a false positive since his more advanced tool reported no errors. They then kept it for a day, to run a "loop test," which also came back with no errors. Then, because apparently it is easier to re-load the OS rather than actually diagnose the issue, they re-loaded my OS clean. (Yay, now I can re-load all my apps, copy 200GB data back on, and THEN we'll see that it is a hardware problem.)
Tomorrow I'll pick it up from Apple and run the AHT again. If it errors out again, I'm not sure what to do...

One note I had neglected to mention is that the bar/band immediately above the keyboard gets very, very hot. Yes, I know that is where the fans are. However, all 12 of the MBP's at the Apple store did not have this extra-hot band, and those are on all day. My little Safari & Mail apps should not cause an overheat situation, on a functioning machine. Apple blamed Google Chrome for the crashes, downplayed the overheating, and downplayed the AHT results.
Update: I went to the Apple store today and took a look at the notebook. They ran their tests, had re-loaded the OS, and performed an undisclosed hardware repair. (They were helpful but vague as to what the actually did on the machine, hardware-wise.) They said their advanced tools & extended Loop Test did not indicate any errors or problems. While still at the store, I ran another quick test with the Apple Hardware Test, which came back with the same 4SNS error as mentioned above. I asked for a refund, which they approved (except they said I have to come back Monday since I bought the machine from Apple Business.)
When I got home, I ran an extended test with the Apple Hardware Test and got a *diffferent* error this time: 4HDD/11/40000000:SATA(0,0).
It's seems strange to me that the AHT shows 2 different errors, and yet the Genius' "advanced " tools find no errors. Thankfully, I will return this one (eventually) get a new unit. Thanks to everyone for helping. --Peter

Apple Hardware Test Error: 4SNS/1/40000001: IDOR-0.958 what's wrong?

Hello
i swapped SSD in MBA A1369 to an OWC 256GB, it worked well since 2 months until yesterday.
When I opened screen to wake up, it showed only blinking folder with question mark so it couldn't find startup volume.
SSD is invisible in Disk utilities and Apple Hardware Test shows: 4SNS/1/40000001: IDOR-0.958.
I don't know what this error means, is it any way to repair it on my own?
If not, memory seller will exchange item, but I'm asking you guys, before shipping.
Thanks in advance

Ask and ye shall receive reilogix...

Your machine is absolutely fine. Run the test again with your power connected.

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.

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,

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.

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.

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

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.

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.

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?
Model Name:
MacBook Pro
Model Identifier:
MacBookPro7,1
Processor Name:
Intel Core 2 Duo
Processor Speed:
2.4 GHz
Number Of Processors:
1
Total Number Of Cores:

3 MB
Memory:
8 GB
Bus Speed:
1.07 GHz
Boot ROM Version:
MBP71.0039.B0B
SMC Version (system):
1.62f7

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.

Test Error 4SNS/1/40000001:VMBS (Corrupt Video)

While my Mac Pro was in an idle state (no active apps processing except for the screensaver), the video became corrupted. It looks like a patchwork quilt of short, colorful horizontal lines and blocks. On reboot, even the Apple splash screen has short horizontal lines running through parts of the screen. The OS is completely unusable, however, I was able to run the diags and came up with this error code:
4SNS/1/40000001:VMBS
I hadn't made any software updates recently, nor made any other changes to the computer, hardware or software. My instinct is that either my graphics card or motherboard are toasted.
Any feedback would be appreciated.
Joe

After going to see the Geniuses, I have no new information. They came to the same conclusion: that it was either the graphics card or the logic board.
Surprisingly, they were not able to narrow it down for me, even with the error code I provided. Their suggestion was that I purchase a new graphics card, try it, and return it if that did not solve the problem. Then bring the system back in for a logic board replacement ($850).
I am hoping that someone on this forum has a better suggestion than that. I'd really like to have more confidence in the problem before I start dumping the cash into it. Thanks!

Hardware test error 4SNS/1/40000000: TB3T-128000, what does this mean?

hello,
I have a macbook aluminium 2008 2,4 ghz 8gb ram 120gb samsung ssd. since last week it has lots of kernel panics, so I did a clean install of osx mavericks, didn't work. Then I tried a hardware test and gave me an mem error (which has something to do with ram) so I installed the original ram bud after another hardware test it gave me this error: 4SNS/1/40000000: TB3T-128000, what does this mean?
thnksss

The precise meaning of AHT result codes is known only to Apple, however, SNS refers to a sensor and TB3T implies a fault with the battery temperature sensor.

2010 17" MacBook Pro i5 Apple Hardware Test Error 4SNS/1/40000000'TmOP

While presenting a keynote the other evening a spinning rainbow wheel was being displayed as I transitioned between several of the slides. That was embarrassing for me and was very concerning seeing as this is a new top of the line machine and is just barely a week old. I ended up deciding to run the Apple Hardware Test by holding the D key during startup. Unfortunately it gave me the following error during the extended test: 4SNS/1/40000000'TmOP
I called Apple earlier today and spoke to a supervisor who told me that this was a normal occurrence in all MacBook Pros. Is this really true? Could someone diagnosis this error further for me as I certainly was not satisfied with the answer I received earlier. Should I exchange the computer within the 14 day return policy for another while I can? If this is just a normal occurrence then I'm okay with that, but something just doesn't seem right here. Please advise me as to how I should proceed, thank you.

Welcome to Apple Support Communities
That's a Temperature Sensor error and if it appears in repeated Hardware tests it most certainly is not normal by any measure. Run the test again and if you get that same thing take it back to the store where you got it, be polite but firm and insist they exchange at no cost.

Error 4SNS/1/40000001:ID2S-0.000

I have an issue with cpu fan running out of control.
I ran Apple Hardware Test and it gave me that errot number.
Does anyone know anything about it ?
Where can I find meaning and action plan ?
Thanks

Most likely a failed device temperature sensor. As noted, contact Apple Service, iMac Service or Apple's Express Lane and get it fixed.
