  Upper Oxygen Sensor, Ft Oxygen Sensor, Sensor Hego, dy1182

• Description:

  This is the genuine Ford upstream heated exhaust gas oxygen sensor, the upper front oxygen sensor that threads into the exhaust ahead of the catalytic converter and reports the air-fuel ratio of the exhaust stream to the powertrain control module so it can trim fuel delivery for correct combustion and emissions. Ford lists it under the base number 9F472 and the catalog name Sensor HEGO, and it serves the upper upstream position. It fits 2011 through 2018 Ford Edge, Flex, and Taurus and related Lincoln models with the 3.5L and 3.7L V6 engine family in the upstream position. A failing upstream oxygen sensor commonly triggers the check-engine light with codes for sensor response or heater-circuit faults, and drivers experience rough idle, hesitation, reduced fuel economy, and failed emissions testing as the module loses accurate feedback and defaults to a fixed fuel strategy. Because the sensor is exposed to extreme exhaust heat and thermal cycling, the ceramic element and internal heater degrade with mileage and can be contaminated by oil or coolant leaks. This genuine Ford sensor arrives with the correct connector, wire length, and thread pitch to seat in the factory bung and plug into the harness without adapters. Verify the exact upstream position and engine displacement for your vehicle before ordering, since the downstream sensor and the opposite-position sensors carry different part numbers. Anti-seize is typically pre-applied to the threads, so avoid contaminating the sensor tip during installation.
