P1130 Subaru Code - Front Oxygen Sensor Circuit Malfunction Open Circuit
Quick Answer
The Powertrain Control Module (PCM) monitors the Heated Oxygen Sensor (HO2S) activity for 60 seconds. Common causes include Faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1, Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 harness is open or shorted, Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

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.
