Code P0130 Subaru Description

The P0130 diagnostic trouble code (DTC) for Subaru vehicles indicates an issue with the O2 (oxygen) sensor circuit in Bank 1 Sensor 1. This sensor is responsible for monitoring the oxygen content in the exhaust gases and providing feedback to the engine control module (ECM) for proper air-fuel ratio adjustments. A malfunction in this circuit can lead to inaccurate readings, affecting the engine's performance, fuel efficiency, and emissions control.

  • Hi I have 2004 Subaru Impreza 2.4 and it have po130 code, already change de o2 sensor but I still the same code. Please can somebody help me

  • It have too a new Catalytic

  • Which sensor did you replaced, front (upstream) or back (downstream)?

  • I have a 2004 Subaru Forrester with P0130 not going away after a new cat and replacing sensor 2x so far. Still the check engine light and code. Any thoughts?

  • hi i have replced upstream and the light is still on do i have to replce the downstream to?

  • You shouldn't have to, the P0130 code is for the upstream sensor only. What model and year is your Subaru?

  • it is B4 2010 stationwagen

  • I checked a national database of repairs an there is nothing else that cause the P0130 other than the sensor itself. Do you have any other symptoms or codes? any exhaust leaks?

  • ok tnx for your ripling
