Oxygen Sensors for Ford F-250 Super Duty (2012-2016) 6.2L Upstream & Downstream

Direct-Fit Oxygen Sensor Set for 2012-2016 Ford F-250 (P473)

What it Does: The complete 4-piece oxygen sensor set monitors exhaust gas composition on the 2012-2016 Ford F-250 to optimize closed-loop air-fuel ratios, maintain catalytic converter efficiency, and eliminate check engine lights.

The Stock Ford F-250 Sensor Degradation

Exhaust gas temperature fluctuations and sustained duty cycles on the Boss 6.2L V8 take a heavy toll on factory oxygen sensors. Over time, silica, carbon fouling, and thermal fatigue coat the internal zirconia sensing elements. This degradation slows sensor switching response times and cross-counts between rich and lean conditions. The ECM compensates with inaccurate short-term and long-term fuel trims, leading to unburned hydrocarbon waste, poor fuel economy, rough idle, and persistent DTCs such as P0130 through P0161, or catalyst false-alarms like P0420 and P0430.

The Engineering Solution

This full 4-sensor replacement kit restores factory closed-loop telemetry across both cylinder banks simultaneously. Built with robust planar ceramic sensing elements and laser-welded stainless steel protective bodies, these sensors resist contamination and thermal shock. Each unit is calibrated to match factory impedance and output curves, featuring direct-fit 4- and 5-wire harness pinouts and factory-length wiring leads. Swapping all four sensors simultaneously eliminates asymmetrical bank readings and resolves cross-bank fueling discrepancies without wire splicing.

Frequently Asked Questions & Fitment Warnings

Does this fit the P473 F-250?

Yes, this is a direct fit for the 2012-2016 Ford F-250 equipped with the Boss 6.2L engine; it does not fit 6.7L Power Stroke diesel models.

Do I need to apply anti-seize when installing these sensors?

Apply high-temperature anti-seize strictly to the threads while ensuring the sensor tip remains completely clean and free of contamination.

The Ford Heavy-Duty Standard

Built to handle severe commercial service and continuous towing loads, these sensors maintain correct stoichiometry under high exhaust gas temperatures so your Super Duty retains its maximum pulling capacity and fuel range.
