Diagnostic Method
Detect a malfunction by measuring the rear oxygen sensor response time during fuel cut.
| (A) | 0.55 V |
| (B) | 0.5 V |
| (C) | 0.2 V |
| (D) | 0.15 V |
| (E) | 0 V |
| (F) | Diagnostic parameter |
| (G) | Normal |
| (H) | Malfunction |
Judge as NG when the following conditions are established.
JUDGMENT VALUE SPECIFICATION
| Malfunction Criteria | Threshold Value |
|---|---|
| Time needed for rear oxygen sensor voltage to change from 0.5 V to 0.2 V | More than 2 s |
Time needed for diagnosis: Less than 1 s
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
