Walker Products 350-34149 oxygen sensor for the 1997-2000 Mercedes-Benz C230 4-cylinder 2.3L measures the oxygen content of the exhaust gas to show combustion efficiency. This Walker Products oxygen sensor is a 4-wire, direct-fit, narrow-band unit for the upstream position.
- Made for its specific application and fitment position, to give the ECU the diagnostic feedback it requires
- Monitors exhaust gases to help reduce pollutants
- Electrodes coated with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Measures oxygen levels to help fine-tune the air-fuel mixture for fuel economy
Quick facts
- Part: Walker Products 350-34149 oxygen sensor
- Fits: 1997-2000 Mercedes-Benz C230 4-cylinder 2.3L
