DTC Setting Condition
| Item | DTC setting condition |
|---|---|
| Main Action | abnormal sensor performance |
| Prerequisite Condition | Upstream oxygen sensor preparation state (measured oxygen sensor tip temperature of 800°C or more or heating time of 30 seconds or more after dew point end) Lambda set point 0.95 to 1.05 Lambda control limit (rich side) 0.9 Over 50g of integrated intake air volume since the start of injection Stable running conditions (the difference between the actual engine speed and the filtered engine speed is 80 RPM or less, the difference between the actual intake air amount and the filtered intake air amount is 25 mg/stroke or less, and the difference between the actual torque and the filtered displayed torque is 120 Nm or less) |
| Trouble Determination | If the Upstream oxygen sensor lambda value is less than 0.90 - rich |
| Diagnosis Time | 100 seconds |
| Threshold Value for Warning Light | 2nd drive cycle |
