Detailed Description

NTK 22134 is a replacement oxygen sensor for downstream left, downstream right, and downstream rear positions depending on vehicle application. It is listed for 2011-2019 Ford Explorer, 2011-2019 Ford Flex, 2015-2019 Ford Taurus, 2011-2019 Lincoln MKT, 2011-2015 Lincoln MKX, 2011-2015 Mazda CX-9, 2011-2014 Ford Edge, 2011-2013 Mazda 6, 2011-2012 Ford Fusion, 2011-2012 Ford Taurus, 2011-2012 Lincoln MKS, 2011-2012 Lincoln MKT, 2011-2012 Lincoln MKZ, and 2011 Mercury Milan. If you are searching for an NTK 22134 oxygen sensor for a Ford Explorer downstream left location or a Lincoln MKX downstream right replacement, this part matches the listed OE application data.

NTK manufactures oxygen sensors with ceramic control technology and extensive production testing to support consistent signal performance and OE specification alignment. This part cross-references Bosch 15383 and DENSO Auto Parts 234-4489 for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Fault codes tied to downstream sensor response
• Incorrect air-fuel feedback from a worn heated O2 sensor
• Emissions test failures caused by sensor degradation
• Replacement needs for B1S2 or B2S2 sensor locations

Installation Notes and Tips

Confirm the exact position before ordering, since NTK 22134 is used in different downstream locations across the covered vehicles. Match the connector, wire count, thread diameter, and harness length to the original sensor, and verify the vehicle year, make, model, and sensor location against the fitment list. For best results, inspect the exhaust threads and wiring routing before installation.

Quality Assurance

NTK is a major original equipment oxygen sensor manufacturer, and this Direct Fit Oxygen Sensor line is manufactured and tested to meet or exceed OE specifications for fit and reliability.
