Nissan Tsuru 99 Catalyst Problem

Hello estimated, I have a Nissan Tsuru 99, which brings a catalyst in the mofle tube, I want to know if there is any way to detect if the catalyst is performing its function, since when I use this car at the time of turning it off it begins to smell of gasoline slightly, already check the hoses, the tank plug, and the tank and there are no leaks, and I have been seeing that there is a engine The car is moving, and Em vez de diminuir a temperatura, começa a subir para um máximo de 3/4

Para verificar, você precisa colocar a máquina de leitura a gás de escape. Em seu estado ideal, deve marcar você:
- CO: 0%
- HC: - 100 ppm
- O2: cerca de 0%
- c.o2: 14-15%

A medida de dióxido de carbono fornece o comportamento ideal do catalisador, deve estar em 14-15% quando o restante das medidas estiver bom.
