DTC Confirmation Test (Using Generic Scan Tool)

WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Before performing test, ensure fuel tank level is 1/4-3/4, ambient temperature is 32-86°F (0-32°C). Ensure EVAP-CPVCSV hoses are installed correctly. Open hood before proceeding.
  1. Start engine. Drive vehicle according to specified driving pattern to set System Readiness Test (SRT) codes. See SYSTEM READINESS TEST  under DRIVE CYCLES. Stop vehicle and go to next step.
  2. Select MODE 1 on scan tool and check SRT status of EVAP system. If EVAP system SRT is complete, system is okay at this time. If EVAP system SRT is incomplete, turn ignition off, wait at least 10 seconds and go to next step.
    3. NOTE: It is not necessary to allow engine to cool before driving vehicle.
  3. Perform driving pattern again. Select MODE 3 on scan tool. If DTC P0455 is set, go to DIAGNOSTIC PROCEDURE . If P0442 is displayed, perform DIAGNOSTIC PROCEDURE for DTC P0442: EVAP CONTROL SYSTEM - SMALL LEAK DETECTED . If DTC P0441 is displayed, go to DIAGNOSTIC PROCEDURE for DTC P0441: EVAP CONTROL SYSTEM - INCORRECT PURGE FLOW . If DTC P0441, P0442 or P0455 is not displayed, go to next step.
  4. Select MODE 1 with scan tool. If EVAP system SRT is complete, system is okay at this time. If EVAP system SRT is not complete, repeat procedure starting in step  3.
