PCM/ECM sets DTC P0130 if the PCM/ECM detects that the front HO2S signal circuit is open.
Item | Detecting Condition | Possible Cause | |
DTC Strategy | Case 1 |
•
Voltage range check | 1. Open in signal harness 2. Open in ground harness 3. Poor connection or damaged harness 4. Faulty Heated O2 Sensor(HO2S) |
Case 2 |
•
Check time for O2 sensor readiness detection(to start feedback control) | ||
Enable Conditions | Case 1 |
•
10V< Battery voltage <16V
•

Case 2 |
•
Minimum time after start versus coolant temperature at start(-40℃ : 90sec./-20℃ : 60sec./0℃ : 53sec./15℃ : 32sec./55℃ : 32sec.) | ||
Threshol Value | Case 1 |
•
0.38V< HO2S < 0.47V | |
Case 2 |
•
O2 sensor operative ready | ||
Diagnostic Time | Case 1 |
•
10 sec. | |
Case 2 |
