Oxygen Sensor for 2016-2017 Mercedes-Benz GLE300d & More - Walker 350-35161

Walker Products 350-35161 oxygen sensor for the 2016-2017 Mercedes-Benz GLE300d 4-cylinder 2.1L and other vehicles measures the oxygen content of the exhaust gas. As an upstream wide-band design, this Walker Products oxygen sensor gauges combustion efficiency from that reading.

• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Electrodes made of a gas-permeable platinum layer
• Monitors exhaust gases to help reduce pollutants
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
• Made for its specific application and fit position, with the diagnostic feedback the ECU requires

Quick facts

• Part: Walker Products 350-35161 oxygen sensor
• Fits: 2016-2017 Mercedes-Benz GLE300d 4-cylinder 2.1L and other vehicles
• Position: Upstream

A failing sensor can mean the engine runs poorly, burns more fuel or lights the malfunction indicator light, but a damaged wiring harness or connector can be behind those signs too, so look both over for physical damage with the engine off before replacing the sensor. Newer vehicles also store fault codes in the ECU, and some of them point to the sensor.
