TESTING CONDITION: Always perform test at a temperature of 5 ° C (41 ° F) or more. WITH CONSULT 1. Start engine and warm it up to normal operating temperature. 2. Turn ignition switch OFF and wait at least 10 seconds. 3. Turn ignition switch ON. 4. Turn ignition switch OFF and wait at least 10 seconds. 5. Start engine and let it idle for at least 70 seconds. 6. Select “PURG FLOW P0441” of “EVAPORATIVE SYSTEM” in “DTC CONFIRMATION” mode with CON- SULT. 7. Touch “START”. If “COMPLETED” is displayed, go to step 7. 8. When the following conditions are met, “TESTING” will be displayed on the CONSULT screen. Maintain the conditions continuously until “TESTING” changes to “COMPLETED”. (It will take at least 35 seconds.) If “TESTING” does not change for a long time, retry from step 2. 9.

During this check, a 1st trip DTC might not be confirmed. WITH GST 1. Lift up drive wheels. 2. Start engine (TCS switch or VDC switch OFF) and warm it up to normal operating temperature. 3. Turn ignition switch OFF, wait at least 10 seconds. 4. Turn ignition switch ON. 5. Turn ignition switch OFF, wait at least 10 seconds. 6. Start engine and wait at least 70 seconds. 7. Set voltmeter probes to ECM terminals 32 (EVAP control system pressure sensor signal) and ground. 8. Check EVAP control system pressure sensor value at idle speed and note it. 9. Establish and maintain the following conditions for at least 1 minute. 10. Verify that EVAP control system pressure sensor value stays 0.1V less than the value at idle speed (mea- sured at step 6) for at least 1 second. 11. If NG, go to Diagnosis Procedure INFOID:0000000007358149 1.
