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.

MacBook unibody, Mac OS X (10.6.7)
