NTK 24474 Oxygen Sensor - Downstream Front

Direct Fit Oxygen Sensor

NTK Oxygen Sensor 24474 is a specific-fit, heated oxygen sensor built for emission control service. It uses a threaded mounting design and a 4-wire configuration with a 9.5-inch harness for direct replacement applications.

Compatible With 2014-2020 Acura RLX, downstream front; 2013-2017 Honda Accord, downstream front; 2015 Acura TLX, downstream front; and 2013-2015 Honda Crosstour, downstream front. This NTK oxygen sensor 24474 is engineered for the listed applications with fit, form, and function aligned to OE requirements.

Key Features

• Heated oxygen sensor for emissions system monitoring.
• Specific-fit design for direct replacement service.
• Threaded mounting type for secure installation.
• 4-wire sensor layout with 9.5-inch harness length.
• NTK 24474 is part of the Direct Fit Oxygen Sensor line.

Detailed Description

NTK 24474 is a direct fit oxygen sensor from the Direct Fit Oxygen Sensor line, developed for import and domestic emission control applications. NTK uses ceramic-based sensor technology and OE-focused manufacturing standards to deliver consistent signal performance and application-specific fitment. For Acura RLX, Honda Accord, Acura TLX, and Honda Crosstour applications, this sensor supports downstream front oxygen sensing where accurate exhaust feedback is required for engine management and emissions control.

This part cross-references Bosch 18050 and DENSO Auto Parts 234-4781 for the same application.

What It Is Used For

• Replacing a failed heated oxygen sensor.
• Restoring exhaust feedback for the engine control system.
• Addressing check engine light conditions related to oxygen sensor faults.
• Correcting drivability issues tied to inaccurate air-fuel monitoring.
• Servicing emissions-related sensor problems on the listed vehicles.

Installation Notes and Tips

Verify the downstream front location and connector match before installation. Confirm thread diameter and harness length against the removed sensor to ensure proper routing and fit. Use the vehicle service procedure for removal and installation on the listed Acura and Honda applications.

Quality Assurance

NTK is a major original equipment oxygen sensor supplier and tests these sensors during manufacturing to meet or exceed OE specifications. Part number 24474 reflects NTK application-specific coverage for the listed fitments.
