OBD II MONITOR SPECIFICATIONS

Key-off Monitor MONITOR STRATEGY Required Sensors/Components Purge VSV Canister pump module Frequency of Operation Once per driving cycle Duration Within 15 minutes (varies with amount of fuel in tank) MIL Operation 2 driving cycles Sequence of Operation None TYPICAL ENABLING CONDITIONS Monitor runs whenever following DTCs not stored P0451, P0452, P0453 (EVAP System) EVAP key-off monitor runs when all of following conditions met - Atmospheric pressure 70 to 110 kPa-a (525 to 825 mmHg-a) Battery voltage 10.5 V or higher Vehicle speed Less than 4 km/h (2.5 mph) Ignition switch off Time after key-off 5, 7 or 9.5 hours Purge VSV Not operated by scan tool Vent valve Not operated by scan tool Leak detection pump Not operated by scan tool Both of following conditions met before key-off Conditions 1 and 2 1. Duration that vehicle is driven 5 minutes or more 2. EVAP purge operation Performed ECT 4.4 to 35°C (40 to 95°F) IAT 4.4 to 35°C (40 to 95°F) TYPICAL MALFUNCTION THRESHOLDS Purge VSV stuck open: - EVAP pressure when vacuum introduction complete Higher than reference pressure x 0.2 Purge VSV stuck closed: - EVAP pressure change after purge VSV open Below 0.3 kPa-g (2.25 mmHg-g)
