Ford OEM – (Front) Left & Right O₂ Sensor – 2020-2024 Explorer ST

Ford OEM – (Front) Left & Right O₂ Sensor – 2020-2024 Explorer ST

These are genuine Ford OEM front oxygen sensors designed specifically for the 2020–2024 Ford Explorer ST equipped with the 3.0L twin-turbo EcoBoost engine.

The Explorer ST uses two upstream O₂ sensors — one per cylinder bank — positioned before the catalytic converters. These sensors provide real-time air/fuel ratio data to the ECU, ensuring precise fueling, drivability, and engine protection under both stock and tuned conditions.

Accurate upstream sensor readings are critical for:

• Proper air/fuel ratio control

• Boost and fueling consistency

• Preventing lean conditions

• Maintaining performance and reliability

Common symptoms of a failing front O₂ sensor include:

• Check engine light

• Rough idle

• Hesitation under boost

• Poor fuel economy

• Inconsistent fuel trims

These are factory-correct OEM replacements with proper connector, wiring length, and calibration for direct plug-and-play installation.

Configuration Options

• Right Side (Bank 1) – Front / Upstream

• Left Side (Bank 2) – Front / Upstream

Please confirm proper bank position before ordering.

Fitment

• 2020–2024 Ford Explorer ST

• 3.0L Twin-Turbo EcoBoost
