• 4-wire design with a 15.35 in. wiring harness length
• Built to OE standards for fit, function, and durability
• Aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination

Product Details

Denso 234-8050 is part of Denso’s Oxygen Sensor - OE Style line, which focuses on exact replacement parts for factory-style service. The sensor is manufactured and tested to OE standards and uses a precision-built design to help ensure first-time fitment on the correct vehicle application. This part cross-references NTK 22069 for the same application.

Compatible With 2019-2024 Ford Edge, downstream; 2019-2023 Lincoln Nautilus, downstream; and 2018-2020 Ford F-150, downstream. For shoppers searching for a downstream oxygen sensor for Ford Edge 2019-2024, Lincoln Nautilus 2019-2023, or Ford F-150 2018-2020, Denso 234-8050 matches the listed OE-style replacement applications.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect exhaust oxygen readings affecting engine management
• Reduced fuel economy caused by a worn sensor
• Slow or inconsistent sensor response from an aging unit
• Emissions test failures tied to oxygen sensor performance

Installation Notes and Tips

Verify the vehicle year, make, model, and downstream position before installation. Compare the connector, wire count, and harness length to the original sensor to confirm a proper match. Because this is a specific-fit replacement, use it only on the listed applications for best results.

Quality Assurance

Denso manufactures this oxygen sensor to OE standards and tests it for replacement accuracy and performance consistency. The design includes a protective aluminum oxide trap layer to help shield the sensing element from contamination and support long service life.
