Function Explanation (DTC Detection Outline)<\/p>\n

\u2022 The PCM closes the purge solenoid valve and CV solenoid valve while the vehicle is being driven, and seals the fuel tank. By opening the purge solenoid valve after sealing the fuel tank, evaporative gas in the fuel tank is inducted into the intake manifold, fuel tank pressure is reduced, and the pressure change of the fuel tank is measured by the fuel tank pressure sensor. If the pressure of the fuel tank does not reach the target vacuum after the specified time has elapsed since the pressure was measured, the PCM determines that there is an evaporative gas leakage. If the PCM determines that refueling was performed before the engine starts, according to the result of the refueling determination, the PCM determines that the fuel-filler cap is open and stores DTC P0457:00 (if PCM determines that refueling is not performed, it stores DTC P0455:00).<\/div>\n
\u2022 If the fuel tank level increases after the engine starts, the PCM determines that refueling is performed by comparing the fuel tank level before one drive cycle with the fuel tank level after engine start.<\/p>\n\n\n\n

Repeatability Verification Procedure<\/p>\n

1. Set the remaining fuel quantity in the fuel tank between 30\u201485 %<\/span>.<\/div>\n
2. Verify that OBD-II information (such as freeze frame data) has been obtained and recorded.<\/div>\n
3. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC<\/a>.)<\/div>\n
4. Start the engine and switch the ignition off after 5 s<\/span> have elapsed.<\/div>\n
5. Leave the vehicle for 6 hours or more<\/span>.<\/div>\n
6. Start the engine and leave it idling for 2 min<\/span>.<\/div>\n
7. Drive the vehicle for 30 min<\/span> at a speed of 50 km\/h {31 mph} or more<\/span> (to increase temperature in fuel tank and generate evaporative gas).<\/p>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 If driving the vehicle for 30 min<\/span> at a speed of 50 km\/h {31 mph} or more<\/span> is not feasible, the vehicle can be driven for a continuous 15 min or more<\/span> with the engine coolant temperature at 80 \u00b0C {176 \u00b0F} or more<\/span>.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
8. Stop the engine.<\/div>\n
9. Leave the vehicle for 1 hours or more<\/span>.<\/div>\n
