Denso 234-4782 Oxygen Sensor - Downstream Front

Denso OE Style Oxygen Sensor for Honda Accord

Denso 234-4782 is a heated, specific-fit oxygen sensor built for direct replacement in select Honda Accord applications. It is engineered for the downstream front position and uses OE-style construction to match the original sensor layout on 2013-2017 Honda Accord models.

Key Features

• Specific-fit oxygen sensor for direct replacement service
• Heated sensor design for faster operating response
• 4-wire configuration with male connector
• Threaded mounting type with 0.708 in. thread diameter
• 9.37 in. wiring harness length for OE-style routing
• Built to OE standards for exact replacement fit and function

OE Style Construction

Denso’s OE Style line is built to match original equipment fitment and sensor performance requirements. The 234-4782 oxygen sensor uses precision-built components for first-time fitment and includes Denso’s aluminum oxide trap layer, which helps protect the ceramic element from silicone and lead contamination. That design supports stable engine management, fuel efficiency, and long service life in the exhaust stream.

This part cross-references Honda 365325G2A01 and NTK 24476 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a worn downstream sensor
• Reduced fuel economy caused by inaccurate exhaust feedback
• Slow sensor response after heat cycling or contamination
• Emissions test failures tied to faulty oxygen sensor output

Installation Notes

Fits 2017 Honda Accord, downstream front. Fits 2013-2016 Honda Accord, downstream front. Confirm connector style, thread size, and harness routing before installation. Use the OE-style mounting location and verify the sensor is installed in the correct exhaust position for proper engine control feedback.

Quality Assurance

Denso manufactures and tests this oxygen sensor to strict OE standards for fit, function, and durability. The 234-4782 is designed as a direct replacement for select Honda Accord applications, with OE-style construction intended to deliver consistent sensor performance.
