Oxygen Sensor for 1986-1993 Mercedes-Benz 300E & More - Walker 350-33023

Walker Products 350-33023 sensor for the 1986-1993 Mercedes-Benz 300E 2.6L / 2.8L / 3.0L and other vehicles is a heated, narrow-band upstream oxygen sensor that reads the oxygen in the exhaust gas so the engine computer can judge combustion efficiency.

• Made for its specific application and fitment position, and returns the diagnostic feedback the ECU requires
• Measures oxygen levels to fine-tune the air-fuel mixture, which helps fuel economy
• A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
• Monitors exhaust gases to help reduce pollutants
• Electrodes are made of a gas-permeable platinum layer

Rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light can mean the oxygen sensor is worn, though its wiring harness or connector can be behind them, so look both over for damage first.

This Walker Products oxygen sensor is a direct-fit replacement for the 1988-1992 Mercedes-Benz 300CE 3.0L and the 1988-1992 Mercedes-Benz 300TE 3.0L as well, and each takes one. Your own car may be one of the others, so search for it in the "Vehicles it fits" section.
