Direct-Fit Oxygen Sensor

NTK 24476 is a direct-fit oxygen sensor built for specific applications and engineered for OE-style fit, form, and function. It uses a heated, threaded design with a 4-wire configuration and a 9.25-inch harness for a clean replacement on compatible emissions systems.

Key Features

• Direct-fit design for specific applications
• Heated oxygen sensor construction
• 4-wire configuration for signal and heater control
• Threaded mounting with 18 mm thread diameter
• 9.25-inch wiring harness length

Detailed Description

NTK 24476 is part of the Direct Fit Oxygen Sensor line, created to streamline replacement selection while maintaining OE-level application coverage. As a downstream front oxygen sensor for 2013-2017 Honda Accord applications, it is built to match the original sensor’s fit and function without requiring a universal adaptation. NTK’s background as a major OE oxygen sensor supplier is reflected in the sensor’s manufacturing focus, with testing used to verify quality and reliability against OE specifications. This part cross-references DENSO Auto Parts 234-4782 for the same application.

What It Is Used For

• Replacing a worn or slow-responding oxygen sensor
• Addressing check engine light concerns related to sensor performance
• Restoring proper exhaust gas feedback to the engine control system
• Correcting drivability issues tied to inaccurate air-fuel monitoring
• Replacing a damaged threaded sensor or harness connection

Installation Notes and Tips

Verify the connector, harness length, thread diameter, and mounting style before installation. This sensor is a specific-fit replacement for 2013-2017 Honda Accord downstream front applications, so confirm the original sensor location and connector match before ordering. Use proper removal tools on the exhaust bung to avoid thread damage during service.
