ABSTRACT:
According to a strategy of monitoring an evaporative purge system, a tank pressure within a fuel tank is monitored and a canister purge valve is shut off if the monitored tank pressure reaches a predetermined vacuum. A purge prohibit code is stored after the monitored tank pressure has reached the predetermined vacuum. A canister purge by the engine is conducted if predetermined conditions are met unless the purge prohibit code is stored.
