DTC Description

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

The ECM tests rear HO2S signal level during the time the lambda target point is being shifted to rich to determine rear HO2S signal stuck.

The ECM sets DTC P227000 if rear HO2S signal is below the predetermined threshold while target lambda point is being shifted to the predetermined value. If the same error code is set in the next driving cycle, the ECM illuminates the MIL.
