4 manufacturer-specific interpretations across 3 manufacturers in the TuningBot DTC database.
BMWThe control module detected an interruption (open circuit) in the Heated oxygen sensor (HO2S) 1, bank 2 circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by BMW.
DodgeThe control module detected that the air-fuel mixture stayed richer than the target despite full corrective control (Heated oxygen sensor (HO2S) 1, bank 1 system). This is the manufacturer-specific definition used by Dodge.
