  Motorcraft™ Upper Oxygen Sensor, Motorcraft™ Ft Oxygen Sensor, Sensor Hego

• Description:

  This genuine Motorcraft heated exhaust gas oxygen (HEGO) sensor is the upstream right-side unit that mounts ahead of the catalytic converter to sample oxygen in the exhaust. Its fast-switching signal lets the powertrain control module fine-tune the air-fuel mixture in real time for the best balance of power, fuel economy, and emissions. Motorcraft catalogs it as an upper Oxygen Sensor (HEGO) in the right/front position. It fits 2015-2021 Ford applications, including F-150, Expedition, and Navigator with the 3.5L EcoBoost twin-turbo V6, and the 1.0L EcoBoost Focus. When this upstream sensor ages or becomes contaminated it responds slowly and reads inaccurately, commonly triggering a check engine light with lean, rich, slow-response, or oxygen-sensor circuit codes and causing poor fuel economy, rough idle, hesitation, and higher emissions. Because it directly governs closed-loop fueling, a degraded sensor is a frequent cause of failed emissions testing. Fit the correct Motorcraft replacement to restore accurate feedback, torque to specification, and route the harness clear of the hot exhaust. The exact Motorcraft unit guarantees correct connector keying, heater circuit, and calibrated response for dependable operation.
