P2279: PCV System Leak

NOTE: The ECM is part of the immobilizer system. If you substitute a known-good ECM, the ECM will have a different immobilizer code. In order for the engine to start, the immobilizer code must be rewritten using the Honda PGM Tester. See IMMOBILIZER SYSTEM  under SELF-DIAGNOSTIC SYSTEM.

On 2004 models, if the scan tool indicates DTC P2279, a leak in the PCV system may exist. To diagnose, see Fig 1 .
