DTC Detecting Condition and Trouble Area
DTC DETECTING CONDITION CHART
| DTC detecting condition | Trouble area |
|---|---|
| P0031: HO2S Heater Control Circuit Low (Sensor 1) Output voltage of A/F sensor heater drive circuit is lower than 6 V even if control duty ratio of A/F sensor heater is lower than 90%. (2 D/C detection logic) |
