xiiii k grande complicação.... ver os erros do EG ( se n estou em falha pelo avatar ) é extremamente facil.
por cima da centralina vais encontrar um cabo com 2 terminais, um deles com 2 fios outro com 3.
desliga a ignição
no de
2 com um moltimentro faz ponte entre os dois terminais.
liga a ignição e conta o numero de vezes k a luz de motor te piscar , ve a duração e o numero de piscadelas e tem atenção se n te faz 2 sequencias diferentes.
cada sequencia dáum codigo de erro.

agora uma coisinha ..... notas alguma diferença nos consumos ? as luz acende mais knd tempo esta humido ou friu ? n notas gds diferenças no andamento ?? tens colectores de escape ? ou mexes-te neles recentemente ?? se a resposta é sim a alguma destas perguntas ,provavelmente o teu problema será a sonda lambda .....
e ai tens 2 opções ,compras uma novas ou mandas anular a k tens na centralina...
