NTK 24305 Air / Fuel Ratio Sensor - Upstream Front

NTK Direct Fit A/F Sensor for Accord

NTK Part Number 24305 is a direct-fit heated air/fuel ratio sensor for select 2004-2007 Honda Accord applications. It is built for the upstream front position and uses a 5-wire design with a specific-fit configuration for straightforward replacement of the original sensor.

NTK is known for OE sensor coverage across import and domestic vehicles, and this Direct Fit 5-Wire A/F Sensor line focuses on correct fit, form, and function for service replacement. For Honda Accord owners searching for an upstream front air fuel ratio sensor, NTK 24305 provides the application-specific design needed for the listed vehicles.

Key Features

• Direct fit air/fuel ratio sensor for select Honda Accord models
• Heated sensor design for faster operating temperature
• 5-wire configuration for the specified application
• Specific-fit replacement for the upstream front position
• 18.000 mm thread diameter with 0.38 thread length
• 11.5 wiring harness length
• Mounting bracket not included

Application Details

Compatible with 2004-2007 Honda Accord, upstream front. This NTK 24305 sensor is intended for the OE-style replacement position on the engine side of the exhaust stream, where accurate air/fuel feedback is critical for fuel control and emissions monitoring. If you are replacing an upstream front Honda Accord air fuel ratio sensor, this part number matches the listed fitment.

This part cross-references Bosch 15401 for the same application.

What It Helps Address

• Check engine light related to air/fuel ratio sensor performance
• Rough idle caused by inaccurate exhaust feedback
• Fuel trim issues from a slow or failing upstream sensor
• Emissions test failures tied to sensor response problems
• Poor drivability from incorrect air/fuel mixture correction

Installation Notes

Verify the connector, wire count, and upstream front location before installation. The 18.000 mm thread diameter and specific-fit design should be matched to the original sensor configuration on the 2004-2007 Honda Accord. Inspect the harness routing and exhaust-side clearance during replacement, and confirm the sensor is installed in the correct upstream position.

Quality Assurance

NTK manufactures oxygen and air/fuel sensors with OE-focused engineering and extensive production testing to help ensure consistent fit and reliable operation. As part of the NGK family of products, NTK supports import and domestic applications with original-equipment-level sensor coverage.
