Walker Products 250-24686 oxygen sensor for the 2010-2013 Mercedes-Benz S400 V6 3.5L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a 4-wire, direct-fit narrow-band unit for the downstream position.
- Electrodes made of a gas-permeable platinum layer
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Measures oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Made for its specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-24686 oxygen sensor
- Fits: 2010-2013 Mercedes-Benz S400 V6 3.5L and other vehicles
- Position: Downstream left, downstream right
- Condition: New
Rough running, higher fuel use or a lit malfunction indicator light can mean the sensor is worn, though a damaged wiring harness or connector can be behind the same signs. Newer vehicles can store fault codes in the ECU that relate to the sensor.
Fits
Besides the 2010-2013 Mercedes-Benz S400 V6 3.5L, the vehicles it fits include the 2007-2012 Mercedes-Benz GL450 V8 4.7L and the 2008-2012 Mercedes-Benz C300 V6 3.0L. Other Mercedes-Benz models are listed in the "Vehicles it fits" section, so look up your own car there. This listing is one sensor, and each downstream position, left or right, takes one.

Frequently Asked Questions
Does this Mercedes C300 oxygen sensor fit the 2008-2012 C300 V6 3.0L?
Yes. Walker Products 250-24686 is listed for the 2008-2012 Mercedes-Benz C300 V6 3.0L. For other cars, look up your model in the "Vehicles it fits" section.
Is this a Mercedes GL450 oxygen sensor for the 2007-2012 GL450 V8 4.7L?
Yes. The 2007-2012 Mercedes-Benz GL450 V8 4.7L is on the fitment list for this downstream sensor, which is listed for the left and right positions.
Is this oxygen sensor narrow-band, and how many wires does it have?
Yes, Walker Products 250-24686 is a narrow-band sensor. It has 4 wires and a direct-fit design.
How do I check an oxygen sensor for damage?
With the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage. A shop can run the electrical tests.
What does the platinum electrode coating do on this sensor?
The electrodes are a gas-permeable platinum layer. A coating protects their surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
