Vipcar Oxygen Sensor 2344490 Downstream O2 Sensor for Ford 2011-2015 — Zirconia, Pre-coated Threads

Vipcar 2344490 is a direct-fit downstream oxygen (O2) sensor designed to replace the factory unit on select Ford, Lincoln, Mazda and Mercury vehicles to restore accurate exhaust oxygen readings.

This Vipcar downstream O2 sensor is built from high-temperature stabilized zirconia with platinum electrodes and a double laser-welded stainless-steel housing for long life and reliable performance. It’s manufactured to meet or exceed original equipment specifications and ships with pre-coated threads for easier installation. Before ordering, verify connector shape and sensor position match your vehicle to ensure fitment.

How does this oxygen sensor affect my vehicle’s emissions and fuel management?

The downstream (post-catalytic converter) oxygen sensor monitors residual oxygen in the exhaust to help the vehicle’s control modules assess catalytic converter efficiency. While it doesn’t control air-fuel mixture like an upstream sensor, a healthy downstream sensor is essential for emissions diagnostics and ensuring the emission control system functions as intended.

• Provides feedback on catalytic converter performance
• Helps the vehicle’s computer detect emissions faults
• Supports accurate trouble-code diagnosis during inspections

Will this Vipcar 2344490 sensor fit my Ford, Lincoln, Mazda, or Mercury?

This part is compatible with a range of models and engine sizes from 2011–2015, including many Ford F-150, Edge, Explorer, Flex, Taurus, Fusion, Transit and several Lincoln, Mazda and Mercury vehicles. Confirm year, engine displacement, and sensor location before purchase, and compare the connector and physical shape to your existing sensor images for a correct match.

• Fits specified Ford models from 2011–2015 (check 3.0L/3.5L/3.7L options)
• Fits Lincoln MKS/MKT/MKX/MKZ 2011–2015 where listed
