The anti-evaporation system prevents the fuel vapors, which consist of the lightest fractions of the hydrocarbons that form in the tank, from discharging into the atmosphere and being suctioned again to be burned.
The system operates especially when the outside temperature is high and the fuel temperature rises, thus increasing the tendency to evaporate. 2 S H U D W L Q J 3 U L Q F L S O H

The canister is connected, by means of two solenoid valves, to two pipes that convey the vapors to the engine intake
manifolds. With the engine running, each solenoid valve is piloted in duty-cycle by the engine control unit according
to engine speed and load, thus putting the canister into communication with the intake manifold and allowing the
suction of the vapors inside the canister. At high engine speed, a venting valve (VISTON valve), connecting the

The fuel vapor sensor generates a OBDII error in case of not controlled fuel vapor emission (not pressurized tank with leakage from the pipes or plug missing).

The causes of destruction of the catalyst inner part are mainly two: •Lead in the fuel, that lowers the conversion level to practically nothing (“lead poisoning”) and irreparably
damages the lambda sensor too;

to cause the melting of the metal support. As a consequence the connector must never, in any circumstances, be disconnected from the coils when the engine is running.
