The purge valves (
A-Fig.2) empty the canister (that holds back the fuel gases that form inside the tank) positioned
on the right side of the engine compartment. 7 K H W Z R Y D O Y H V D U H ¿ W W H G X Q G H U Q H D W K W K H L Q W D N H P D Q L I R O G Z K L F K K D V W R E H U H P R Y H G W R J H W W R W K H Y D O Y H V The purge valves are driven by the injection control units according to a strategy set by their calibration software.
In the circuit is a pump positioned under the canister that controls the system’s seal; this pump is driven according to the operating time.
The control unit receives the information if the circuit is sealed, so the more time spent loading the pressure into the tank, the greater the possibility is that the system turns on the pilot lamp.
