Oxygen Sensor for 2000-2003 Mercedes-Benz ML55 AMG & More - Walker 250-24609

Walker Products 250-24609 oxygen sensor for the 2000-2003 Mercedes-Benz ML55 AMG V8 5.5L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This 4-wire, direct-fit narrow-band sensor lets the engine control unit monitor the air-fuel ratio.

• Narrow-band, 4-wire design that gives the ECU the diagnostic feedback it requires
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen level so the air-fuel mixture can be fine-tuned for fuel economy
• Monitors exhaust gases to help reduce pollutants

A failing sensor can show up as the engine running poorly, higher fuel consumption or a lit malfunction indicator light. These signs can mean the sensor is worn, though a damaged wiring harness or connector can be behind them too, so look over both with the engine off and cool. This listing is one sensor, and the 2000-2003 Mercedes-Benz ML55 AMG V8 5.5L takes one.
