Diagnostic Method
Detect a malfunction by measuring the time from fuel cut completed until the rear oxygen sensor voltage begins to rise.
| (A) | 0.3 V |
| (B) | 0 V |
| (C) | Diagnostic parameter |
| (D) | Malfunction |
| (E) | Normal |
Judge as NG when the following conditions are established.
JUDGMENT VALUE SPECIFICATION
| Malfunction Criteria | Threshold Value |
|---|---|
| Output voltage value of rear oxygen sensor | Less than 0.2V |
| Elapsed time | More than value of Map |
VALUE SPECIFICATION - MAP
| Average value of intake air amount (g/s (oz/s)) | 19 (0.7) | 20.00 (0.71) | 21.00 (0.74) | 22.00 (0.78) |
| Elapsed time (ms) | 4576 | 4500 | 4000 | 4000 |
Time needed for diagnosis: Less than 1 s
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
