  Rear Oxygen Sensor, Sensor Exhaust Gas Oxygen, dy1280

• Description:

  This is a heated exhaust gas oxygen (HEGO) sensor for the 2015-2019 Ford Transit gasoline engine. The oxygen sensor threads into the exhaust and measures the oxygen content of the exhaust stream, sending a signal the powertrain control module uses to trim the air-fuel mixture and, depending on position, to monitor catalytic-converter efficiency. An internal heater brings the sensor to operating temperature quickly for accurate readings soon after startup. A buyer shopping for this sensor is typically responding to a check-engine light with oxygen-sensor, fuel-trim, or catalyst-efficiency codes, degraded fuel economy, rough or uneven running, hesitation, or a failed emissions test. Oxygen sensors age and slow down over time as the element becomes contaminated by combustion byproducts, oil, or coolant, causing lazy switching and poor fuel control. Installing the correct genuine sensor restores accurate feedback, proper fueling, and emissions compliance. Ford catalogs this component as the Sensor - Exhaust Gas Oxygen. Use anti-seize sparingly on the threads only if the sensor does not arrive pre-coated, route the harness away from the exhaust and moving parts, and avoid contaminating the sensor tip during installation. Genuine Ford component matched to the original connector and thread specification.
