Diagnostic Method
Detect a malfunction by measuring the rear oxygen sensor response time after fuel cut.
| (A) | 0.5 V |
| (B) | 0.2 V |
| (C) | 0 V |
| (D) | Diagnostic parameter |
| (E) | Voltage at normal condition |
| (F) | Response time at normal condition |
| (G) | Voltage at abnormal condition |
| (H) | Response time at abnormal condition |
Judge as NG when the following conditions are established.
JUDGMENT VALUE SPECIFICATION
| Malfunction Criteria | Threshold Value |
|---|---|
| Rear oxygen sensor voltage value | Less than 0.5 V |
| Elapsed time | More than 2500 ms |
Time needed for diagnosis: Less than 1 s
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
