EVAPORATIVE EMISSION CONTROL SYSTEM (CALIFORNIA TYPE)

This model complies with California A ir Resources Board (CARB) evaporative emission requirement. Fuel vapor from the
I
fuel tank is routed into the evaporative emission (EVAP) canister where it is absorbed and stored while the engine is
"
stopped. When the engine is running and the evaporative emission (EVAP) purge control solenoid valve is open, fuel vapor
in the EVAP canister is drawn into the engine through the throttle body.
