The ECM/PCM sets DTC P2414 when upstream O2 sensor voltage is higher than 3.7 V.
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Plausibility Check Sensor mechanically not mounted | 1. Poor connection 2. Open or short power/ground in signal circuit 3. HO2S(S1) |
Enable Conditions |

Threshold Value |
•
Upstream O2 sensor voltage > 3.1V | |
Diagnostic Time |
•
25 sec. | |
MIL ON Condition |
•
2 driving Cycles |
※ S1 : upstream oxygen sensor / S2 : downstream oxygen sensor
