MALFUNCTION CRITERIA AND THRESHOLD VALUE REFERENCE
| Malfunction Criteria | Threshold Value |
|---|---|
| Shortest time change from rich (500 mV O2 output) to lean (200 mV) when voltage reduces from 550 mV to 150 mV | > 491 milliseconds |
| Time at 550 mV or more | > 2 seconds |
Time Needed for Diagnosis: 1 time
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
