Luzes "Ets Off" no quadro

Hello friends, how are my car is a cavalier z 24 mod 97 American and from a date for here I have presented a fault with an indicator light on the "ETS OFF" board and this happens after walking a while and when the car turns on the car as it is pulling a little I already did the engine transmition service the coils of the teach I do not know if for the same reason we put the scanner and the only thing that marks me is that transmission is heated but the mechanic tells me Que a transmissão é boa que esse erro seja normal, espero que alguém possa me ajudar a dar uma orientação para resolver o problema antes da mão, muito obrigado

Good evening, what you have to see first is to disconnect the transmission plug (oviously would be canceling the transmission sensors) and if the problem is the envelope sensor, the problem will no longer give you the problem I tell you this just to check it because when the sensors can You caught part of the day and you do not have the problem, then you walk the sensor, because what happens is that the sensor is heated and the fault comes you have to wait for it to cool and when you put the Scanner, não parece ser branqueado porque o Todabia não está queimado, que mecanismo faz o 3.1 ou 2.2 Go, ai de qualquer coisa que você me avise.
