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 | DTC Detecting Condition | Possible Cause | |
|---|---|---|---|---|
| P0130 | 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 | 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. | |||
