0.020” EONV EVAP Monitor Operation:DTCsMonitor executionMonitor SequenceSensors/Components OKMonitoring DurationP0456 (0.020” leak)P260F (Evaporative System Monitoring Processor Performance)Once per key-off when entry conditions are met during drive. 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
Typical 0.020 EONV EVAP monitor malfunction thresholds:P0456 (0.020” leak): < 0.75 in H 2 O pressure build and< 0.50 in H 2 O vacuum build over a 45 minute maximum evaluation timeJ1979 EONV EVAP monitor Mode $06 DataTest ID Comp ID Description for J1850 Units$3C $81 EONV Positive Pressure Test Result and Limits in H 2 0$3C $82 EONV Negative Pressure (Vacuum) Test Result and Limits in H 2 0$3C $83 Normalized Average of Four EONV Tests Results and Limits(where 0 = pass, 1 = fail)unitlessNote: Default values (0.0 in H 2 0) will be displayed for all the above TIDs if the evap monitor has nevercompleted. The appropriate TID will be updated based on the current or last driving cycle, default values willbe displayed for any phases that have not completed.FORD MOTOR COMPANY REVISION DATE: APRIL 28, 2004 PAGE 33 OF 131
