Walker Products 250-24419 right oxygen sensor for the 1998-2000 Mercedes-Benz C280 V6 2.8L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It passes that reading to the ECU as diagnostic feedback for the downstream right position.
- Narrow-band sensor with 4 wires
- Measures exhaust oxygen content and monitors the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gas
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24419 oxygen sensor
- Fits: 1998-2000 Mercedes-Benz C280 V6 2.8L and other vehicles
- Position: Downstream right
- Condition: New
A failing oxygen sensor can show up as a rough-running engine, higher fuel consumption or a malfunction indicator light, though those signs have other possible sources. Before replacing it, look the sensor, its wiring harness and the connector over for physical damage with the engine off and cool.
Fits
The 1998-2000 Mercedes-Benz C280 V6 2.8L, the 1998-2000 Mercedes-Benz C43 AMG V8 4.3L and the 1998-2000 Mercedes-Benz CLK320 V6 3.2L take this direct-fit sensor, one per car in that position, and so do more vehicles. This listing is a single right-side sensor, and the left side is ordered separately. If your car is not named here, look it up by year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the Mercedes C280 oxygen sensor for a 1998-2000 model with the V6 2.8L?
Yes. Walker Products 250-24419 fits the 1998-2000 Mercedes-Benz C280 V6 2.8L as the downstream right sensor, and that position takes one.
Is this Walker Products oxygen sensor narrow-band or wideband?
Walker Products 250-24419 is a narrow-band sensor with 4 wires and an M18 - 1.5 thread. Its electrodes carry a gas-permeable platinum layer.
Is this oxygen sensor an upstream or a downstream unit?
This sensor is for the downstream right position. The left side is a separate part.
What does the coating on this oxygen sensor do?
The coating protects the electrode surfaces from contamination and erosion caused by combustion residue and particulates in the exhaust gas.
What does this narrow-band sensor report to the ECU?
It measures the oxygen content of the exhaust gas and monitors the air-fuel ratio. The ECU uses that reading as diagnostic feedback on combustion efficiency.
