Those codes are proprietary to Apple technicians. No public list exists of what they mean. SNS has something to do with a sensor. You need to bring your mac to an Apple store or AASP for diagnosis.

Thanks, I'll make a genius appointment at my local Apple Store.

I read your post today... and I have the same error 4SNS/1/40000000 TB3T-128.000
Have you met a Genius ? If yes... what did he say ?
Ps... sorry if my english isn't correct... I'm french.
MacBook Pro (13-inch End 2009), Mac OS X (10.6.8)

I had the same error and took my 2009 13' macbook pro to the genius bar today. For me, since I had my battery replaced at the store a couple of weeks ago, and the machine is working fine, it was a non-issue.
The genius told me to just ignore it. He checked their internal database and apparently it is a common issue. He explained that the new battery don't have the same sensor as the old one, and the machine is complaining about that. He ran the in-store diagnostic tool on the machine and everything looked fine.
Though I didn't ask whether the new battery has a different sensor and is not compatible, or the sensor is simply not necessary with the new battery... or upgrading the OS would update the sensor map... etc. I can think of a few many questions afterwards.
I trust that as long as the machine and the battery is working fine, it is a non-issue.

That error is a temperature sensor error. It should be looked into.

My 2009 MacBook Pro has the exact same 4SNS/1/40000000: TB3T-128.000 error.
And a few weeks ago I, too, had the battery replaced by Apple, but I'll take it in because of another issue.
Thanks for posting your experience.

This error is a Battery Sensor Error. Your machine is basically not detecting the senor.
Did you just replace the battery?

Yes, Apple did replace my battery. After this, the hardware test detected this Battery Sensor Error.
I took my 2009 MacBook Pro to the Genuis Bar, and the Apple diagnostics stated there were NO errors in my hardware.
Their test has superceded the original hardware test designed in 2009.
Apple claims their diagnostic test is more complete than the old provided hardware test so my MacBook Pro hardware is good.

Indeed, there is the Apple Hardware Test that are provided to users but as techs we can run Apple Software Diagnostics which run slighlty different tests. Glad to hear it worked out. :-)
