Diagnostic Method 2
Detect the malfunction by the cumulative value obtained from the amount of variation in λ change.
- Abnormality Judgment
Judge as NG when the following conditions are established.
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| Cumulative value obtained from the amount of variation in λ change Σ |(lambda(n) - lambda(n-1)) - (lambda(n-1) - lambda(n-2))| |
< Value from Map | P014C and P014D |
MAP (AT MODEL EXCEPT FOR PZEV)
| Cumulative value obtained from the amount of variation in λ Σ |lambda(n) - lambda(n-1)| |
0.00 | 5.00 |
| Cumulative value obtained from the amount of variation in λ change | 0.00 | 3.00 |
MAP (MT MODEL EXCEPT FOR PZEV)
| Cumulative value obtained from the amount of variation in λ Σ |lambda(n) - lambda(n-1)| |
0.00 | 3.00 |
| Cumulative value obtained from the amount of variation in λ change | 0.00 | 9.00 |
MAP (PZEV AT MODEL)
| Cumulative value obtained from the amount of variation in λ Σ |lambda(n) - lambda(n-1)| |
0.00 | 3.50 |
| Cumulative value obtained from the amount of variation in λ change | 0.00 | 3.50 |
MAP (PZEV MT MODEL)
| Cumulative value obtained from the amount of variation in λ Σ |lambda(n) - lambda(n-1)| |
0.00 | 2.00 | 4.00 |
| Cumulative value obtained from the amount of variation in λ change | 0.00 | 7.00 | 9.00 |
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 obtained from the amount of variation in λ change Σ |(lambda(n) - lambda(n-1)) - (lambda(n-1) - lambda(n-2))| |
≥ Value from Map | P014C and P014D |
Time Needed for Diagnosis: 90 seconds
