Malfunction Threshold
The amplitude output by rear A/F sensor (bank 1, sensor 1) is less than the value shown in the table for at least 5 seconds. The malfunction threshold value changes depending on the mass airflow (MAF) sensor value.
| MAF sensor value [MAF Sensor] | Malfunction threshold value |
|---|---|
| 10 g/s (0.35 oz/s) | Less than 0.012 |
| 20 g/s (0.71 oz/s) | Less than 0.012 |
| 30 g/s (1.06 oz/s) | Less than 0.019 |
| 40 g/s (1.41 oz/s) | Less than 0.025 |
| 50 g/s (1.76 oz/s) | Less than 0.032 |
