Monitor will runup to 2 times per day, or 90 cumulative minutes per day (whichever comesfirst)noneEONV Processor, Canister Vent Solenoid, Fuel Tank Pressure Sensor, FuelLevel Input, Vapor Management Valve, CAN communication link45minutes in key-off state if fault present. Tests will likely complete quicker ifno fault is present.Typical 0.020” EONV EVAP monitor entry conditions:Entry conditions seen just prior to engine off Minimum MaximumEngine off (soak) time3 - 6 hoursTime since engine start-up 20 minutes 50 minutesAmbient Temperature at start-up 40 o F 95 o FBattery Voltage11 voltsNumber of completed tests in 24hr cycle 2Cumulative test time in 24hr cycle90 minutesFuel level 15% 85%No severe slosh conditions seen just prior to key-offTypical 0.020” EONV EVAP key-off abort conditions:Tank pressure at key-off > 1.5" H 2 0 during stabilization phase (indicates excessive vapor)Tank pressure not stabilized for tank pressure offset determinationRapid change in tank pressure > 0.5"H 2 0 (used for refuel/slosh detection)Rapid change in fuel level > 5% (used for refuel/slosh detection)Battery voltage < 11 VoltsRapid change in battery voltage > 1 VoltLoss of CAN networkCanister Vent Solenoid fault detectedDriver turns key-onFORD MOTOR COMPANY REVISION DATE: APRIL 28, 2004 PAGE 32 OF 131
