DTC Description

WARNING: This page is about a different variant/trim than selected.

The ECM monitors the long-term air-fuel ratio correction value in the idle state, and when the value below a certain value, the ECM recognizes a failure and sets DTC P2BF100.

* Off-Idle: The engine speed is lower than the normal idle speed due to the inconsistency of the intake air amount and fuel amount.
