DTC DETECTING CONDITION CHART
| DTC detecting condition | Trouble area |
|---|---|
| P2A01: O2 Sensor Circuit Range/Performance (Sensor 2) Stuck lean: Output voltage of HO2S signal circuit is lower than 0.4 V (A/F mixture: lean state) for 40 sec. and difference between HO2S signal circuit MAX voltage and HO2S signal circuit MIN voltage is lower than 0.2 V. Stuck rich: Output voltage of HO2S signal circuit is higher than 0.85 V (A/F mixture: rich state) for 40 sec. and difference between HO2S signal circuit MAX voltage and HO2S signal circuit MIN voltage is lower than 0.2 V. High output performance malfunction: Output voltage of HO2S signal circuit is lower than 0.6 V (A/F mixture: lean state) for specified time even if A/F mixture based on A/F sensor has been rich state after fuel cut. Low output performance malfunction: Output voltage of HO2S signal circuit is higher than 0.1 V (A/F mixture: rich state) even if fuel cut is activated for 8 sec. (2 D/C detection logic) |
