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.
