Walker Products 350-34448 oxygen sensor for the 2013-2016 Peugeot 301 and other vehicles measures the oxygen in the exhaust gas. This 4-wire, narrow-band sensor is made for its specific application and position, and it sends the diagnostic feedback the ECU needs.
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports normal fuel economy
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-34448 oxygen sensor
- Fits: the 2013-2016 Peugeot 301 and other vehicles
- Position: Upstream, downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can be behind those signs too, so find the cause before buying a sensor. With the engine off and cool, look all three over for physical damage.
Fits
The 2003-2009 Peugeot 307 4-cylinder 2.0L and the 2003-2004 Volvo S60 5-cylinder 2.5L are among the vehicles this oxygen sensor fits. If your car is not named here, look it up in the "Vehicles it fits" section to see whether this sensor is listed for it.
