| DESCRIPTION |
P013A-00:
- HO2S: Slow response (during transition from rich to lean)
P013B-00:
- HO2S: Slow response (during transition from lean to rich)
|
| DETECTION CONDITION |
Determination conditions |
P013A-00:
- The response speed of the HO2S input signal when the air/fuel ratio is fluctuated from rich to lean is slow.
|
P013B-00:
- The response speed of the HO2S input signal when the air/fuel ratio is fluctuated from lean to rich is slow.
|
| Preconditions |
