The PCM monitors front HO2S signal level during part load or full load operation to check if the fornt HO2S is mechanically attached to the exhaust gas pipe while the vehicle is running. The PCM sets DTC P2414 if front HO2S signal is within the predetermined threshold. If the same error code is set in the next driving cycle, the PCM illuminates the MIL.
