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. Then, gas in the fuel tank is inducted into the intake manifold and the pressure in the fuel tank is decreased by opening the purge solenoid valve, and the pressure change in the fuel tank is measured using the fuel tank pressure sensor. If the pressure in the fuel tank decreases below the target negative pressure during the specified period from the pressure measurement (malfunction determination time (1)), positive pressure is inducted to the fuel tank via the intake manifold by closing the purge solenoid valve and opening the CV solenoid valve. After positive pressure is inducted to the fuel tank, the fuel tank is sealed, opening\/closing of the purge solenoid valve is performed repeatedly, and the pressure change in the fuel tank is monitored at that time (malfunction determination time (2)). If the amount of pressure change veers towards negative pressure exceeding the malfunction determination threshold, the PCM determines that there is clogging between the fuel tank pressure sensor and fuel tank, and stores a DTC.<\/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
