Walker Products 250-24468 oxygen sensor for the 2003-2011 Mercedes-Benz G55 AMG V8 5.5L and other vehicles measures the oxygen content of the exhaust gas. Each Walker part number is made for its specific application and position and sends the diagnostic feedback the ECU needs.
- Monitors exhaust gases to help reduce pollutants
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24468 oxygen sensor
- Fits: 2003-2011 Mercedes-Benz G55 AMG V8 5.5L and other vehicles
- Position: downstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
A failing sensor can show up as a poorly running engine, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. If the sensor is the cause, this one replaces it. First, with the engine off and cool, look over the sensor, wiring harness and connector for physical damage, because damage there can shorten the sensor's life.
Fits
It is listed for a wide range of Mercedes-Benz models, led by the 2003-2011 G55 AMG V8 5.5L, the 2003-2004 C200 4-cylinder 1.8L and the 2005-2010 SLK55 AMG V8 5.5L, and it is a direct-fit replacement for these vehicles. This listing is one sensor, and each sensor position takes one. Driving a different Mercedes-Benz? Look up its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this a Mercedes C200 oxygen sensor for 2003-2004 models with the 4-cylinder 1.8L?
Yes. Walker Products 250-24468 is listed for the 2003-2004 Mercedes-Benz C200 4-cylinder 1.8L, and each sensor position on that engine takes one.
Is the Walker Products oxygen sensor narrow-band or wideband?
Narrow-band. The Walker Products 250-24468 is a 4-wire narrow-band sensor made for its specific application and fitment position.
What are the electrodes on this oxygen sensor made of?
The electrodes are a gas-permeable platinum layer, and the coating on their surfaces guards against contamination and erosion from combustion residue and particulates.
Does this narrow-band oxygen sensor help fuel economy?
Yes. It reads how much oxygen is in the exhaust so the air-fuel mixture can be adjusted, which helps fuel economy.
Is this oxygen sensor upstream or downstream?
The catalog lists 250-24468 for downstream, upstream left, upstream right, downstream left and downstream right positions, depending on the application.
