This section provides general information and checks that you can perform at home.
If there is a suspicion that the emission control system is malfunctioning, first check the fuel system and the ignition system. Diagnosis of some emission control systems requires specialized tools and equipment.
It must be remembered that the most common cause of failure of emission control systems is a broken or disconnected wire or vacuum hose, so first check their connection and integrity.
An information plate with important data and information on the regulation of the monitoring and reduction of toxicity of exhaust gases is glued to the back of the hood. There is also a label with diagrams and identification of the location of the vacuum hoses for controlling the control system and reducing the toxicity of exhaust gases.
