• Description:

  This is a genuine Motorcraft upstream heated exhaust gas oxygen (HEGO) sensor that installs ahead of the catalytic converter and measures the oxygen content of the exhaust so the powertrain control module can adjust injector delivery and keep the air-fuel mixture near the ideal ratio for efficient, low-emission combustion. As the front, pre-catalyst sensor it drives the primary closed-loop fueling correction rather than monitoring catalyst efficiency. It is a cross-platform application for 2013-2020 Ford and Lincoln models, covering Escape 1.6L, C-Max 2.0L, and Focus 2.0L across SE, SEL, Titanium, Hybrid, and Energi configurations, and it carries the Ford service cross-reference DS7Z-9F472-A, the upper oxygen sensor position in that family. A failing upstream sensor typically sets P0130 through P0135 oxygen-sensor codes, lights the check-engine lamp, and causes rough idle, hesitation, surging, poor fuel economy, and emissions-test failure as fueling drifts and the module reverts to open loop. The Motorcraft catalog name is Oxygen Sensor, and the part ships with the matched sealed connector and heater circuit for a direct fit. Apply anti-seize to the threads only, keep the sensing tip free of silicone, grease, and solvents, and torque to the exhaust-bung specification to protect the ceramic element. Fitting this genuine Motorcraft sensor restores accurate exhaust feedback, steady closed-loop operation, and proper catalyst protection on the compact Ford and Lincoln vehicles it was cataloged to serve. Because it is built to the original heater resistance and switching response, the module reads it without relearning, making replacement a straightforward restoration of factory air-fuel control and driveability.
