  Lower Oxygen Sensor, Sensor Exhaust Gas Oxygen, dy1331

• Description:

  This is the genuine Ford oxygen sensor, the exhaust gas oxygen sensor that measures oxygen content in the exhaust stream so the engine controller can fine-tune the fuel mixture and verify catalytic converter operation. Cataloged by Ford as an exhaust gas oxygen sensor, it threads into the exhaust and feeds the powertrain control module the signal it needs for closed-loop fuel control. This part serves 16-23 Transit Connect, Fusion and Escape applications in the downstream sensor position as applicable. Owners look for this sensor when the check engine light sets oxygen sensor or catalyst-efficiency codes, when fuel economy drops, or when the engine runs rough or fails an emissions test, all of which can trace to a lazy or failed sensor. Because the sensor is exposed to extreme exhaust heat and combustion byproducts, its sensing element ages and slows or becomes contaminated over time, which is a common cause of emissions codes and reduced efficiency. A failing oxygen sensor degrades fuel control and emissions. Installing the correct genuine sensor restores accurate exhaust readings and proper closed-loop operation. As an original Ford component it matches the thread, heater circuit, and connector exactly so it reads accurately and plugs into the factory harness. Confirm the engine, sensor position, and connector against your vehicle before ordering, and use anti-seize sparingly on the threads as directed during installation.
