Delphi ES20223 rear oxygen sensor for the 2005-2009 Subaru Outback H6 3.0L, the 2010-2014 Outback H6 3.6L and other vehicles measures the oxygen in the exhaust and sends that reading to the engine computer. This Delphi oxygen sensor gives the computer the data it uses to manage fuel and emissions.
- Delphi planar technology covers older, conical-design sensors
- Smart design consolidates SKUs without using long wires
- Patented protective sensor coating helps prevent contamination
- Validated for all fuel types, including ethanol blends like E85
- Tested to 150,000 miles, plus 2,000 hours of severe thermal testing
Quick facts
- Part: Delphi ES20223 oxygen sensor
- Fits: the 2005-2009 Subaru Outback H6 3.0L, the 2010-2014 Outback H6 3.6L and other vehicles
- Position: Rear, rear left, rear right
- Condition: New
A failing oxygen sensor can show up as a check engine light, rough running or poorer fuel economy. These signs alone don't prove the sensor is the problem; an exhaust leak near the sensor can throw off its readings too.
Fits
The 2005-2009 Subaru Outback H6 3.0L, the 2010-2014 Outback H6 3.6L, the 2008-2009 Subaru Legacy H6 3.0L and the 2010-2014 Legacy H6 3.6L take this oxygen sensor, as does the 2003-2004 Toyota 4Runner V6 4.0L, and so do other vehicles. This listing is one sensor; those Subarus take two and the 2003-2004 Toyota 4Runner V6 4.0L takes one. Open the "Vehicles it fits" section to check your exact model and engine.
