Typical Malfunction Thresholds
WARNING: This page is about a different car, the 2004 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
TYPICAL MALFUNCTION THRESHOLDS
| Detection Criteria | Threshold |
|---|---|
| Case 1: | |
| Following conditions are met: | 1,2 and 3 |
| 1. Cumulative heated oxygen sensor monitor time | 260 seconds or more (AT) 190 seconds or more (MT) |
| 2. Time while heated oxygen sensor voltage is less than 0.05V | 156 seconds or more (AT) 114 seconds or more (MT) |
| 3. Maximum heated oxygen sensor rich time (0.45V or more) | Less than 20 seconds |
| Case 2 : | |
| Number of heated oxygen sensor voltage "switching" | 0 times or less |
| "Switching" is counted when the sensor signal crosses the minimum or maximum voltage | |
| Minimum voltage | 0.4 V or less |
| Maximum voltage | 0.5 V or more |
