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 fuel in tank) MIL Operation 2 driving cycles Sequence of Operation None TYPICAL ENABLING CONDITIONS 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 more Vehicle speed Below 4 km/h (2.5 mph) Ignition switch OFF Time after key off 5 or 7 or 9.5 hours Canister pressure sensor malfunction (P0451, P0452 and P0453) Not detected 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 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 ON (open) Less than 0.3 kPa-g (2.25 mmHg-g)

Purge Flow Monitor MONITOR STRATEGY Required Sensors/Components Purge VSV Canister pump module Frequency of Operation Once per driving cycle Duration Within 10 minutes MIL Operation 2 driving cycles Sequence of Operation None TYPICAL ENABLING CONDITIONS Monitor runs whenever following DTCs not present None Engine Running ECT 4.4°C (40°F) or more IAT 4.4°C (40°F) or more Canister pressure sensor malfunction Not detected Purge VSV Not operated by scan tool EVAP system check Not operated by scan tool Battery voltage 10 V or more Purge duty cycle 8% or more TYPICAL MALFUNCTION THRESHOLDS Both of following conditions met Conditions 1 and 2 1. EVAP pressure change when purge operation started Less than 0.1 kPa-g (0.75 mmHg-g) 2. EVAP pressure change during purge operation when vent valve closed Less than 0.4 kPa-g (3.0 mmHg-g)
