DTC Detection Logic
To judge malfunctions, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1 signal fluctuates according to fuel feedback control.
| DTC No. | Trouble diagnosis name (Trouble diagnosis content) |
DTC detecting condition | Possible Cause | |
|---|---|---|---|---|
| P0130 | A/F SENSOR1 (B1) [Air fuel ratio (A/F) sensor 1 (bank 1) circuit] |
A) | The A/F signal computed by ECM from the A/F sensor 1 signal is constantly in a range other than approx. 2.2 V. |
|
| B) | The A/F signal computed by ECM from the A/F sensor 1 signal is constantly approx. 2.2 V. | |||
| P0150 | A/F SENSOR1 (B2) [Air fuel ratio (A/F) sensor 1 (bank 2) circuit] |
A) | The A/F signal computed by ECM from the A/F sensor 1 signal is constantly in a range other than approx. 2.2 V. | |
| B) | The A/F signal computed by ECM from the A/F sensor 1 signal is constantly approx. 2.2 V. | |||
