SDYYDS Upstream + Downstream Oxygen O2 Sensor Kit for Ford 1.6L EcoBoost (2013-2019) — 2-piece plug-and-play with heater

Two OE-style oxygen sensors (one upstream, one downstream) engineered to replace worn factory units on 1.6L EcoBoost Ford models — plug-and-play fit for easy swap-out.

If your check engine light points to an O2 sensor or your vehicle is running rough, this SDYYDS 2-piece kit gives you both the upstream and downstream sensors needed to restore correct exhaust oxygen readings. The set directly replaces OE part numbers DS7Z-9F472A (upstream) and BV6Z-9G444A (downstream), listed as 234-5068 and 234-4577. Each sensor is designed for turbocharged 1.6L engines and fits multiple Ford models without cutting, splicing, or modification.

Which vehicles and engines does this sensor kit fit?

This kit is built for Ford 1.6L L4 EcoBoost turbo applications. It covers specific model years and trims where those OE part numbers were used from factory. Always verify compatibility with your VIN or compare the original part numbers before purchase.

• 2013–2016 Ford Escape 1.6L Turbo
• 2014–2019 Ford Fiesta ST 1.6L Turbo
• 2014–2016 Ford Transit Connect 1.6L Turbo
• Replaces OE DS7Z-9F472A (upstream) and BV6Z-9G444A (downstream)

How easy is installation and what should I expect?

These sensors use the factory connector and mounting interfaces for a direct replacement that requires no cutting or rewiring. Basic mechanical skills and common hand tools are sufficient, though a proper oxygen sensor socket or wrench speeds the job. If you lack experience, professional installation is recommended to avoid cross-threading or connector damage.

• Exact plug-and-play electrical connectors
• Direct thread and mounting dimensions to match factory locations
• Recommended: oxygen sensor socket and anti-seize on threads if not pre-coated
• Professional installation supported by SDYYDS technical help

What are the performance and reliability considerations?

These replacement sensors are manufactured to meet the signaling and durability expectations of factory units for the specified vehicles. They measure exhaust oxygen levels for the engine control module to adjust fuel trim and emissions controls. SDYYDS backs the kit with a 12-month warranty and after-sales technical support for fitment or functionality concerns.

• Specifically calibrated for 1.6L EcoBoost narrowband/heater circuits
• Heater elements included for fast warm-up and accurate readings
• 12-month warranty with responsive online support
• Replacement parts available if manufacturing defects appear

Will replacing both sensors help resolve diagnostics codes?

Replacing faulty upstream or downstream sensors often clears codes tied to oxygen sensing, fuel trim, or catalytic converter efficiency. However, codes can also stem from exhaust leaks, wiring faults, or catalytic damage, so confirm diagnostics before replacing parts. If both sensors show wear, swapping the pair prevents mismatch between old and new sensor behavior.

• Common codes addressed: O2 sensor circuit, lean/rich fuel trim flags, catalyst efficiency
• Check wiring and exhaust for leaks to avoid repeat faults
• Use a scan tool to verify post-replacement readiness monitors

Who is this for: The SDYYDS 2-piece oxygen sensor set is aimed at DIY mechanics and professional technicians maintaining Ford 1.6L EcoBoost vehicles (Escape, Fiesta ST, Transit Connect) that require OE-equivalent upstream and downstream sensors. It suits owners replacing aging sensors, addressing emissions or drivability codes, or preparing a vehicle for inspection. If you need exact fitment, compare the listed OE numbers with the parts currently on your vehicle and contact SDYYDS support for help.
