Walker Products 350-34338 right oxygen sensor for the 1998-2000 Mercedes-Benz C280 V6 2.8L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is made for its specific application and position, and it gives the ECU the diagnostic feedback it needs.
- Monitors exhaust gases to support lower emissions
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Monitors the air-fuel ratio through the oxygen content of the exhaust gas
- Electrodes made of a gas-permeable platinum layer
- Narrow-band sensor with 4 wires
Quick facts
- Part: Walker Products 350-34338 oxygen sensor
- Fits: the 1998-2000 Mercedes-Benz C280 V6 2.8L and other vehicles
- Position: Downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can produce those signs too, so find the cause before buying. This listing is one sensor for the downstream right position; other positions are ordered separately.
Fits
The 1998-2000 Mercedes-Benz C43 AMG V8 4.3L and the 1998-2000 Mercedes-Benz CLK320 V6 3.2L take this sensor too, along with many other vehicles. Driving something else? Enter your car's year, make and model in the "Vehicles it fits" section to find it.

Frequently Asked Questions
Will this Mercedes C280 oxygen sensor work on a 1998-2000 Mercedes-Benz C280 V6 2.8L?
Yes. Walker Products 350-34338 is the downstream right oxygen sensor for the 1998-2000 Mercedes-Benz C280 V6 2.8L, and that position takes a single sensor.
Is the Walker Products 350-34338 a narrow-band or wideband sensor?
Walker Products 350-34338 is a narrow-band sensor with 4 wires. It measures the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency.
What are the electrodes on this downstream right oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from combustion residue and particulates in the exhaust gas.
How do I check this downstream right oxygen sensor for damage?
With the engine off and cool, look over the sensor, wiring harness and connector for physical damage. Newer vehicles may also store fault codes in the ECU that a shop can read.
Does Walker Products 350-34338 send the ECU the feedback it needs?
Yes. Walker Products makes each part number for its specific application and fitment position, so this sensor provides the diagnostic system feedback the ECU requires.
