Detailed Description

NTK is a long-standing supplier of original equipment oxygen sensors, and the 24114 reflects that OE-focused approach. Built with ceramic technology developed in-house, this sensor is manufactured to deliver fit, form, and function aligned with factory requirements. It is extensively tested during production to help ensure reliable performance that meets or exceeds OE specifications.

This part cross-references Bosch 18048 and DENSO Auto Parts 234-4461 for the same application. It is a direct-fit oxygen sensor for 2012-2014 Acura TL, 2010-2013 Acura MDX, 2011-2013 Honda Odyssey, 2011-2012 Acura RL, and 2010-2012 Acura ZDX in the downstream front position. Search terms such as NTK 24114 oxygen sensor, Acura TL downstream front oxygen sensor, and Honda Odyssey B2S2 replacement oxygen sensor all point to this application.

Common Issues This Sensor Can Address

• Fault codes related to oxygen sensor response or heater circuit performance
• Rough idle or drivability concerns caused by inaccurate exhaust feedback
• Failed emissions inspection tied to a worn downstream sensor
• Reduced fuel control accuracy from a degraded sensor signal
• Check engine light conditions associated with the listed sensor location

Installation Notes and Tips

Verify the downstream front position and connector routing before installation. Match the 4-wire layout, 18 mm thread size, and harness length to the original sensor on the vehicle. For best results, confirm the exact model year and engine application against the vehicle’s service information before replacing the sensor.

Quality Assurance

NTK manufactures oxygen sensors with OE application coverage and extensive production testing to support consistent quality and reliability. The 24114 is built to meet the fit and performance expectations of the listed Acura and Honda applications.
