| DTC No. | Trouble diagnosis name (Trouble diagnosis content) | DTC detecting condition | Possible cause |
|---|---|---|---|
| P0037 | HO2S2 HTR (B1) [Heated oxygen sensor 2 heater (bank 1) control circuit low] | The current amperage in the heated oxygen sensor 2 heater circuit is out of the normal range. (An excessively low voltage signal is sent to ECM through the heated oxygen sensor 2 heater.) |
|
| P0038 | HO2S2 HTR (B1) [Heated oxygen sensor 2 heater (bank 1) control circuit high] | The current amperage in the heated oxygen sensor 2 heater circuit is out of the normal range. (An excessively high voltage signal is sent to ECM through the heated oxygen sensor 2 heater.) |
|
| P0057 | HO2S2 HTR (B2) [Heated oxygen sensor 2 heater (bank 2) control circuit low] | The current amperage in the heated oxygen sensor 2 heater circuit is out of the normal range. (An excessively low voltage signal is sent to ECM through the heated oxygen sensor 2 heater.) |
