HO2S (LH) slow response-rich to lean |
| DETECTION CONDITION |
- During a deceleration fuel shut-off event, the PCM monitors how quickly the HO2S (LH) switches from rich to lean. The measured rate of the rich to lean switch is compared to a calibrated error threshold value. The threshold value takes into account the level of oxygen in the catalyst, which has an impact on how quickly the rich to lean switch occurs. The test fails if the measured value is slower than the threshold value.

| POSSIBLE CAUSE |
- Exhaust leaks before or near the HO2S (LH)
- HO2S (LH) malfunction
