Lexus: trac off + check engine warning 92 SC400 solution

Hi! every body !
I had the same problem for over a year and a half, and I took the car to
many places, but nothing could be done: finally I fpund the solution by my
self:
- I looked at the engine next to the belt (the long belt in the front that
connect every thing ) Isaw a little black double-wire comming strait from
the engine and it's going back inside: it was half scratched by the belt:
so I attached together with some tape AND THAT'S IT
