  Lower Oxygen Sensor, Sensor Exhaust Gas Oxygen

• Description:

  This is the genuine Ford heated exhaust gas oxygen sensor for the 2018 through 2022 EcoSport. Mounted in the exhaust downstream of the catalytic converter, it measures the residual oxygen in the exhaust stream and sends a voltage signal to the powertrain control module so the computer can confirm catalyst efficiency and keep fuel trim within spec. A worn or contaminated sensor slows its switching response and skews the air and fuel mixture, which is why a buyer shopping for this part is usually chasing an illuminated check engine light with a P0420 catalyst efficiency code or a related post catalyst oxygen sensor code, along with reduced fuel economy, a rough idle, hesitation, or a failed emissions test. The Ford catalog name for this component is Oxygen Sensor. It arrives with the correct terminal connector and pigtail for a direct plug in fit, and the threads are pre coated so no additional anti seize is needed. Route the harness clear of the exhaust and driveline and torque the sensor to the Ford service specification. Installing a matched genuine sensor restores accurate feedback to the engine controller and clears the fault once the monitor completes its drive cycle.
