  Ft Oxygen Sensor, Sensor Hego, dy847

• Description:

  This is a genuine Ford heated exhaust gas oxygen (HEGO) sensor, catalogued as Oxygen Sensor and identified at dealer catalogs as the upper, upstream (front) sensor. Mounted ahead of the catalytic converter, it measures oxygen content in the exhaust stream and reports it to the powertrain control module, which uses the signal to trim the air-fuel ratio for correct closed-loop fueling, efficient combustion, and clean emissions. Its integrated heater brings the sensing element to operating temperature quickly after a cold start so the engine reaches closed-loop control sooner. This sensor is used across a wide range of 1999-2014 Ford applications, and because it spans many years and vehicle lines it is served as a broad multi-vehicle upstream oxygen sensor rather than a single-model part. A worn or contaminated sensor typically sets an oxygen sensor or fuel-trim check engine code and can cause poor fuel economy, rough or surging idle, hesitation, a rotten-egg smell, or a failed emissions test. Installing a genuine Ford HEGO sensor restores accurate feedback so the module can hold the target air-fuel ratio. It matches the factory connector, thread, and calibration for a direct fit. Apply anti-seize sparingly only if the threads are not pre-coated, avoid contaminating the sensor tip, torque to specification, and clear codes after installation. Confirm the correct upstream position and application for your vehicle before ordering.
