Delphi ES20189 Oxygen Sensor Sensor Replacement - O2

The Delphi ES20189 is a direct-fit replacement oxygen sensor (O2 sensor) engineered to OE specifications. As a global original equipment manufacturer, Delphi builds every O2 sensor to the same standards used in vehicle production, delivering accurate exhaust gas measurement and reliable engine management performance.

The oxygen sensor—also known as an O2 sensor or lambda sensor—monitors the level of oxygen in the exhaust stream and feeds that data to the engine control module (ECM). This allows the ECM to maintain the optimal air-fuel ratio, maximizing fuel efficiency, minimizing harmful emissions, and preventing costly catalytic converter damage.

Key Features:

• Advanced Planar Technology – Planar sensor element with integrated heater reaches operating temperature in as little as six seconds for faster closed-loop activation and reduced cold-start emissions
• Patented Protective Sensor Coating – Shields the sensing element against silicone, phosphorous, and other fuel and oil additives that are a leading cause of sensor failure
• OE-Validated Durability – Tested to 150,000 miles and subjected to 2,000 hours of severe thermal cycling to ensure long-term reliability
• Broad Fuel Compatibility – Validated for use with gasoline and ethanol-blend fuels, including E85
• OE Connectors and Wire Lengths – Features factory-matched connectors and wire lengths for straightforward installation without cutting or splicing
• Smart SKU Design – Planar construction allows this sensor to cover older conical-style sensor applications, consolidating replacement SKUs
• Built to OE Standards – Manufactured by a global OE supplier with over 100 years of automotive engineering experience

The Delphi ES20189 oxygen sensor is always new—never remanufactured—and built to meet or exceed original equipment specifications for accurate readings and dependable emissions control.
