Walker Products 350-64042 oxygen sensor for the 2010-2012 Subaru Outback H4 2.5L and other vehicles measures the oxygen in the exhaust gas. Every Walker Products oxygen sensor is made for its specific application and fitment position, and it sends the diagnostic feedback the ECU needs.

• Monitors the air-fuel ratio in the exhaust for combustion efficiency
• Wide-band, 4-wire air-fuel ratio design
• Electrodes made of a gas-permeable platinum layer
• Coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases
• Helps the engine computer fine-tune the air-fuel mixture, which supports fuel economy and lower emissions

Quick facts

• Part: Walker Products 350-64042 oxygen sensor
• Fits: 2010-2012 Subaru Outback H4 2.5L and other vehicles
• Position: Upstream
• Condition: New

A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the malfunction indicator light. These signs alone do not prove the sensor is at fault, since a vacuum leak can also make an engine run rough. Check the sensor, wiring harness and connector for physical damage as well.

Fits

The same oxygen sensor also fits the 2010-2012 Subaru Legacy H4 2.5L. This listing is one sensor, and the upstream position takes just that one.
