OBD2P0130
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.
What it means
O2 Sensor Circuit.
Severity
moderateCan drive but may experience reduced fuel efficiency and performance.
Summary
P0130 indicates a malfunction in the oxygen sensor circuit for bank one's upstream (pre-catalytic converter) O2 sensor.
Symptoms
- Diminished fuel efficiency
- Black smoke from exhaust
- Poor engine performance
- Service engine soon light illuminated
Common Causes
- Defective oxygen sensor
- Rich or lean exhaust conditions due to poor engine performance
- Damaged, disconnected, or faulty wiring and connectors
- Exhaust leaks
Diagnosis
- Check for ignition misfire codes, throttle position sensor issues, manifold air pressure problems, or mass air flow sensor malfunctions.
- Inspect wiring harnesses near hot exhaust pipes and cylinder heads for damage.
- Test battery voltage, terminals, and alternator output.
- Use a diagnostic scanner to retrieve trouble codes and freeze frame data.
- Check fuses related to the O2 sensor system.
Fixes
- Replace faulty oxygen sensor or repair damaged wiring and connectors.
