Diagnostic Method 1
WARNING: This page is about a different variant/trim than selected.
Detect the malfunction depending on the average value of time necessary for λ to inverse the air fuel ratio from "Lean → Rich → Lean" to "Rich → Lean → Rich".
Judge as NG when the following conditions are established.
JUDGMENT VALUE SPECIFICATIONS
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| Average value of time necessary for λ to inverse the air fuel ratio to Lean → Rich → Lean | More than 250 ms | P015A |
| Average value when λ is lean | More than 260 ms |
JUDGMENT VALUE SPECIFICATIONS
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| Average value of time necessary for λ to inverse the air fuel ratio to Rich → Lean → Rich Average value when λ is rich | More than 420 ms More than 430 ms | P015B |
Time needed for diagnosis: 90 s
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
