Code P1130 Subaru Description
The P1130 Subaru code indicates a malfunction in the front oxygen sensor circuit due to an open circuit. The front oxygen sensor, also known as the upstream oxygen sensor, plays a crucial role in monitoring the air-fuel mixture in the exhaust gases before they enter the catalytic converter. This information is essential for the engine control module to adjust the fuel injection accordingly for optimal combustion. An open circuit in the sensor's circuitry disrupts this communication, leading to inaccuracies in the fuel mixture, potentially causing poor engine performance, reduced fuel efficiency, and increased emissions. If left unaddressed, this issue can lead to further damage to the catalytic converter and other engine components.
Common Causes of P1130 Subaru
- Faulty front oxygen sensor
- Wiring or connector issues in the sensor circuit
- Corrosion or damage to the sensor
- Exhaust leaks near the sensor
- Issues with the engine control module
Symptoms of P1130 Subaru
- Check Engine Light illuminated on the dashboard
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
- Increased emissions
How to Fix P1130 Subaru
- Begin by locating the front oxygen sensor in the exhaust system.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion.
- Test the sensor using a multimeter to check for proper voltage and resistance.
- Replace the front oxygen sensor if it is found to be faulty.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1130 Subaru
The cost of repairing a front oxygen sensor circuit malfunction can vary depending on the make and model of the vehicle and the location of the repair. On average, the cost of replacing an oxygen sensor ranges from $200 to $400, including parts and labor. Additional costs may apply if other components need replacing or if diagnostic time is required to pinpoint the issue. It's recommended to consult with a trusted mechanic or auto repair shop for a more accurate cost estimate based on your specific circumstances.

10. Are there any preventive measures I can take to avoid OBDII code P1130 related to the front oxygen sensor circuit malfunction in my Subaru?
- Regular maintenance, such as keeping up with scheduled tune-ups and replacing oxygen sensors as recommended, can help prevent this code from appearing.
Discuss the causes and fixes for P1130 Subaru OBDII Code
-
Replaced o2 sensor before you would start the car after light was cleared the light would come right on now with the light cleared and the new part in the light comes on 20 to 30 seconds after running and the same code comes back
-
What model and year is your Subaru? You could have a blown fuse or broken O2 sensor wire.
-
2002 wrx ok did a volt test at 02sensor I have with the car running 13. 82 coming from two wires and I have 3.82 coming from the other two wires if that helps at all I replaced the relay but not the fuse I am getting readings so I don't believe it would be the fuse
-
The next step is to check continuity from the O2 sensor connector to the ECM.
If the wires are OK, the either you got a bad new O2 sensor (which is possible) or a bad ECM.
