  • 4-wire narrow-band design
  • Made for its specific application, with the diagnostic feedback the ECU requires
  • Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
  • Gas-permeable platinum layer on the electrodes
  • Monitors exhaust gases to help reduce pollutants

Quick facts

  • Part: Walker Products 350-34256 oxygen sensor
  • Fits: 2002-2010 Lexus SC430 V8 4.3L and other vehicles
  • Position: Upstream, downstream, upstream 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, but other faults cause the same signs. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage before you replace anything.

Fits

This oxygen sensor is a direct-fit replacement for a wide range of Lexus and Toyota models, including the 2001-2007 Lexus GS430 V8 4.3L and the 2001-2006 Lexus LS430 V8 4.3L.

Is the Walker Products 350-34256 a narrow-band or wideband sensor?

Walker Products 350-34256 is a narrow-band oxygen sensor with 4 wires.

What can a failing oxygen sensor do to fuel economy and emissions?

A failing oxygen sensor can lead to rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Other faults cause the same signs, so a shop can read the stored codes.

Does the sensor have a coating on its electrodes?

Yes. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates, and the electrodes have a gas-permeable platinum layer.
