Ford OEM – (Rear) O₂ Sensor – 2020-2024 Explorer ST
This is a genuine Ford OEM rear oxygen sensor designed specifically for the 2014–2019 Fiesta ST 1.6L EcoBoost.
The rear O₂ sensor, located after the catalytic converter, monitors exhaust gas composition to ensure proper catalyst efficiency and emissions system performance. Accurate readings are essential for preventing check engine lights and maintaining proper ECU operation.
Common symptoms of a failing rear O₂ sensor include:
-
Check engine light (often catalyst efficiency codes such as P0420)
-
Failed emissions testing
-
Reduced fuel efficiency
-
Inconsistent post-catalyst readings
This is a direct-fit OEM replacement featuring factory-correct connector, wiring length, and calibration for seamless installation.
