NTK 24434 Oxygen Sensor - Downstream

Direct Fit Oxygen Sensor for Acura and Honda

NTK 24434 is a direct fit heated oxygen sensor built for specific downstream applications on select Acura TSX and Honda Accord models. It is engineered to match OE fit, form, and function for the B1S2 position, helping maintain accurate exhaust feedback in the emissions control system.

As part of NTK’s Direct Fit Oxygen Sensor line, this sensor reflects the brand’s focus on OE-style replacement coverage for import and domestic vehicles. NTK uses ceramic manufacturing expertise and production testing to support consistent sensor performance for applications like the 2009-2014 Acura TSX and 2008-2012 Honda Accord.

Key Features

• Direct fit, specific application oxygen sensor
• Heated sensor design for faster operating readiness
• 4-wire configuration with 8-inch wiring harness length
• 18 mm threaded mounting type
• Built for downstream B1S2 placement
• OE-style replacement for Acura TSX and Honda Accord applications

Application Details

NTK 24434 is a downstream oxygen sensor for 2009-2014 Acura TSX and 2008-2012 Honda Accord models. It is a direct fit replacement for the B1S2 oxygen sensor position and is intended for vehicles that require a threaded, heated, specific-fit sensor. This part cross-references Bosch 18100 for the same application.

What This Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect exhaust oxygen readings at the downstream sensor location
• Emissions system faults tied to B1S2 sensor failure
• Rough or inconsistent fuel control caused by inaccurate sensor feedback
• Replacement needs after sensor aging, contamination, or electrical wear

Installation Notes and Tips

Verify the vehicle’s year, make, model, and downstream B1S2 position before ordering. The sensor uses a threaded mounting design and a 4-wire heated configuration, so connector style and harness routing should be checked against the original part. For best results, compare the original sensor length and thread size to the replacement before installation.

Quality Assurance

NTK manufactures oxygen sensors with OE-specification targets and tests them during production for quality and reliability. The brand’s OE supply background and ceramic manufacturing expertise support consistent fitment and performance for direct replacement applications such as the Acura TSX and Honda Accord.
