Diagnostic Method 1
Detect the malfunction by checking "Cumulative value of time when A 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) and | < 0.35 | P014C |
| Average value of time necessary for λ to inverse the air fuel ratio to Lean - Rich - Lean | > 0.01 s | |
| (Cumulative value of time when λ changes from lean - rich)/(Time during which diagnosis is in progress) and Average value of time necessary for λ to inverse the air fuel ratio to Rich - Lean - Rich |
> 0.61 > 0.01 s |
P014D |
Time needed for diagnosis:
120 s (CVT model)
90 s (MT model)
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
