Canister pressure sensor malfunction (P0452, P0453) Not detected Purge VSV Not operated by scan tool EVAP system check Not operated by scan tool Atmospheric pressure 70 to 111 kPa-a (525 to 833 mmHg-a) Battery voltage 10 V or higher (IAT Below 50°C) or 12 V or higher (IAT 50°C or higher) Purge duty cycle 8% or more Typical Malfunction Thresholds (for 100 L (26.4 US gal) Fuel Tank) 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) Typical Malfunction Thresholds (for 144 L (38 US gal) Fuel Tank) 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 0.15 kPa-g (1.1 mmHg-g) MONITOR RESULT Refer to CHECKING MONITOR STATUS
. CONFIRMATION DRIVING PATTERN Connect the Techstream to the DLC3. 1. Turn the ignition switch to ON and turn the Techstream on. 2. Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation). 3. Turn the ignition switch off and wait for at least 30 seconds. 4. Turn the ignition switch to ON and turn the Techstream on [A]. 5. Start the engine and wait 15 minutes or more [B]. 6. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [C]. 7. Read the Pending DTCs. HINT: If a pending DTC is output, the system is malfunctioning. 8. 3UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0441; Evapor... |
