Walker Products 350-34226 oxygen sensor for the 1994-1996 Mercedes-Benz C220 4-cylinder 2.2L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. Each Walker part number is made for its specific application and fitment position, and it sends the diagnostic feedback the ECU needs.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
Quick facts
- Part: Walker Products 350-34226 oxygen sensor
- Fits: 1994-1996 Mercedes-Benz C220 4-cylinder 2.2L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. A damaged wiring harness or connector can be behind these signs too, so find the cause before you buy a sensor.

Frequently Asked Questions
Is the 1994-1996 Mercedes-Benz C220 4-cylinder 2.2L covered by this upstream oxygen sensor?
Yes. Walker Products 350-34226 is a direct-fit upstream oxygen sensor for the 1994-1996 Mercedes-Benz C220 4-cylinder 2.2L.
Is this Walker Products oxygen sensor a narrow-band or a wideband type?
Walker Products 350-34226 is a narrow-band sensor with four wires, made for the upstream position.
Is this upstream oxygen sensor sold as a single piece?
Yes. This listing is one oxygen sensor, and the upstream position takes one.
What can a failing oxygen sensor do to the engine?
The engine can run poorly, fuel consumption and exhaust emissions can rise, or the malfunction indicator light can come on. With the engine off and cool, you can look over the sensor, wiring harness and connector for physical damage.
What protects the electrodes on this oxygen sensor?
The electrodes have a gas-permeable platinum layer, and the coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
