Walker Products 350-34083 oxygen sensor for the 2010-2013 Mercedes-Benz S400 V6 3.5L and other vehicles measures exhaust oxygen to gauge combustion efficiency. As a Walker Products oxygen sensor, it is a 4-wire, direct-fit narrow-band design.
- Sensor provides the diagnostic feedback the ECU requires for its specific application and position
- Measures oxygen levels to fine-tune the air-fuel mixture for fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34083 oxygen sensor
- Fits: 2010-2013 Mercedes-Benz S400 V6 3.5L and other vehicles
- Position: Downstream left, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption or a lit check-engine light. Those signs alone do not prove the sensor is at fault, since a vacuum leak can look much the same. With the engine off and cool, the sensor, wiring harness and connector can also be inspected for physical damage.
Fits
This direct-fit narrow-band oxygen sensor suits the 2010-2013 Mercedes-Benz S400 V6 3.5L, the 2007-2012 Mercedes-Benz GL450 V8 4.7L, the 2008-2012 Mercedes-Benz C300 V6 3.0L and many other vehicles. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this a Mercedes C300 oxygen sensor for the 2008-2012 C300 V6 3.0L?
Yes. Walker Products 350-34083 is listed for the 2008-2012 Mercedes-Benz C300 V6 3.0L as a direct-fit sensor for the downstream left and downstream right positions.
Does this work as a Mercedes GL450 oxygen sensor on a 2007-2012 GL450 V8 4.7L?
Yes. The 2007-2012 Mercedes-Benz GL450 V8 4.7L is covered by this sensor. For a different car, look up its year and engine in the "Vehicles it fits" section.
Is the Walker Products 350-34083 a narrow-band or wideband sensor?
Walker Products 350-34083 is a narrow-band oxygen sensor with four wires and a direct-fit design.
What can a failing downstream oxygen sensor cause?
Poor running, higher fuel consumption or a lit malfunction indicator light can be signs of a failed sensor. A shop can confirm the actual cause.
What does the coating on this oxygen sensor do?
The coating shields the electrode surfaces from contamination and erosion caused by residue and particulates in the exhaust gas. The electrodes themselves are a gas-permeable platinum layer.
