Denso 234-4580 Oxygen Sensor - Downstream Front

Denso 234-4580 Oxygen Sensor for Honda

Denso 234-4580 is an OE Style heated oxygen sensor built for exact replacement and first-time fit. It is engineered for the downstream front position on select Honda Pilot and Honda Ridgeline applications, with a threaded mounting design and a 4-wire male connector for direct replacement service.

Key Features

• OE Style oxygen sensor for precise replacement fit
• Heated sensor design for faster operating response
• Specific fit application for select Honda vehicles
• 4-wire configuration with male connector
• Threaded mounting type with 0.708 in. thread diameter
• 24.88 in. wiring harness length
• Aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination

Product Details

This Denso oxygen sensor is built to meet strict OE standards for fit and function. The 234-4580 uses Denso’s OE Style construction to match the original sensor layout on 2012-2015 Honda Pilot and 2012-2014 Honda Ridgeline models in the downstream front position. Denso’s protective trap layer is designed to shield the sensing element from contamination, helping maintain accurate exhaust feedback, stable engine performance, and fuel efficiency over time. This part cross-references Honda 36532RN0A01 and NTK 24468 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback from a worn downstream sensor
• Reduced fuel economy caused by inaccurate exhaust readings
• Slow sensor response after contamination or age-related wear
• Fitment issues from using the wrong connector or thread style

Installation Notes and Tips

Fits 2012-2015 Honda Pilot, downstream front. Fits 2012-2014 Honda Ridgeline, downstream front. Confirm the connector style, thread diameter, and sensor position before installation. Use the vehicle’s original routing path for the 24.88 in. harness to avoid strain or heat damage. Verify the exhaust threads are clean before threading in the sensor to help ensure proper sealing and accurate readings.

Quality Assurance

Denso manufactures and tests this OE Style oxygen sensor to strict original-equipment standards for consistent fit and dependable operation. The 234-4580 is precision built for direct replacement service on the listed Honda applications.
