Diagnostic Method 2
Detect the malfunction by calculating the average amplitude of l.
- Abnormality Judgment
Judge as NG when the following conditions are established.
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| Average value for λ amplitude | > 0.07 (AT model) > 0.1 (MT model) |
P015A and P015B |
Time Needed for Diagnosis: 11250 time(s) x 8 ms
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.
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| Average value for λ amplitude | ≤ 0.07 (AT model) ≤ 0.1 (MT model) |
P015A and P015B |
