DTC P1447: EVAP System Purge Flow Monitoring: Notes

WARNING: This page is about a different car, the 1998 Nissan Pathfinder and 1998 Infiniti QX4. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If DTC P0510 and P1447 are both stored in memory, diagnose DTC P0510 first.

NOTE: Using the following diagnostic procedure assumes the presence of a current (hard) DTC or the ability to duplicate the setting of the DTC using described procedures (see DTC CONFIRMATION), conducting a test drive under conditions stored in freeze frame data or intermittent recreation procedures. See TESTING PROCEDURE under SELF-DIAGNOSTIC SYSTEM in TESTS W/CODES - INTRODUCTION article. If DTC cannot be duplicated, proceed to TESTS W/O CODES article for diagnosis by symptom.
