Walker Products 350-34517 oxygen sensor for the 2004 Nissan Pathfinder V6 3.5L measures the oxygen in the exhaust gas to show combustion efficiency.

  • Measures oxygen levels to fine-tune the air-fuel mixture for fuel economy
  • Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio
  • Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
  • Monitors exhaust gases to help reduce pollutants
  • Electrodes made of a gas-permeable platinum layer

Quick facts

  • Part: Walker Products 350-34517 oxygen sensor
  • Fits: the 2004 Nissan Pathfinder V6 3.5L
  • Position: Downstream left, downstream right
  • Condition: New

A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Before you replace the sensor, rule out damage by looking over its wiring harness and connector when the engine is cool, and read any fault codes stored in the ECU.

Frequently Asked Questions

Is 350-34517 the right Pathfinder oxygen sensor for the 2004 Nissan Pathfinder V6 3.5L?

Yes. Walker Products 350-34517 is a direct-fit oxygen sensor for the 2004 Nissan Pathfinder V6 3.5L, in the downstream left and downstream right positions.

What type of oxygen sensor is the Walker 350-34517?

Walker Products 350-34517 is a narrow-band oxygen sensor with four wires and an M18 - 1.5 thread.

What can a failing oxygen sensor do to the engine?

A failed sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light.

Does the Walker 350-34517 send feedback to the ECU?

Yes. Walker Products 350-34517 is made for its specific application and fitment position and gives the ECU the diagnostic feedback it requires.

What are the electrodes on this oxygen sensor made of?

The electrodes are made of a gas-permeable platinum layer, and a coating covers the electrode surfaces to resist contamination and erosion from combustion residue.
