Diagnostic Method 1
Detect the malfunction by checking "Cumulative value of time when λ changes from lean → rich" in comparison to "Time during which diagnosis is in progress".
- Abnormality Judgment
Judge as NG when the following conditions are established.
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| (Cumulative value of time when λ changes from lean → rich) / (Time during which diagnosis is in progress) | < 0.39 (except for PZEV model) < 0.39 (PZEV model) |
P014C |
| > 0.61 (AT model) > 0.63 (PZEV model) |
P014D |
Time Needed for Diagnosis: 90 seconds
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
- Normality Judgment
Judge as OK and clear the NG if the following conditions are established.
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| (Cumulative value of time when λ changes from lean → rich) / (Time during which diagnosis is in progress) | ≤ 0.39 (except for PZ model) ≤ 0.39 (PZ model) |
P014C |
| ≥ 0.61 (except for PZ model) ≥ 0.63 (PZ model) |
P014D |
Time Needed for Diagnosis: 90 seconds
