Diagnosis 1
WARNING: This page is about a different variant/trim than selected.
Detect the malfunction by checking "Cumulative value of time when λ changes from lean → rich" in comparison to "Time during which diagnosis is in progress".
Judge as NG when the following conditions are established.
JUDGMENT VALUE SPECIFICATION
| Malfunction Criteria | Threshold Value | DTC |
|---|---|---|
| (Cumulative value of time when λ changes from lean → rich)/(Time during which diagnosis is in progress) Average value of time necessary for λ to inverse the air fuel ratio to Lean → Rich → Lean | Less than 0.39 More than 40 ms | P014C |
| (Cumulative value of time when λ changes from lean → rich)/(Time during which diagnosis is in progress) Average value of time necessary for λ to inverse the air fuel ratio to Rich → Lean → Rich | More than 0.61 More than 25 ms | P014D |
Time needed for diagnosis: 8 ms x 3750time(s)
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
