Denso 234-4313 Oxygen Sensor - Downstream Left or Downstream Right

Denso 234-4313 Oxygen Sensor Overview

Denso 234-4313 is a specific-fit heated oxygen sensor built to OE-style standards for direct replacement on select Nissan and Suzuki applications. It is engineered for accurate exhaust monitoring, stable engine management, and a first-time fit on downstream right or downstream left positions where listed.

The Denso OE Style line focuses on exact replacement dimensions and sensor performance. This oxygen sensor uses a threaded mounting design, a male connector, 4 wires, and a 10.63-inch wiring harness length to match the original configuration on covered vehicles.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct replacement installation
• Threaded mounting type with 0.708-inch thread diameter
• 4-wire configuration with male connector
• 10.63-inch wiring harness length
• OE Style replacement for select Nissan NV, Frontier, Pathfinder, Xterra, and Suzuki Equator applications
• Part number 234-4313 for accurate ordering and cross-reference

Product Details

This Denso oxygen sensor is manufactured and tested to OE standards and built for exact replacement on covered Nissan and Suzuki vehicles. The sensor’s aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination, supporting consistent exhaust feedback and long service life. For buyers searching for a downstream right oxygen sensor for a 2005-2012 Nissan Frontier, Pathfinder, or Xterra, or a downstream left sensor for a 2011-2012 Suzuki Equator, 234-4313 is the direct-fit OE-style option.

This part cross-references ACDelco 213-3066 and NTK 24247 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
• Rough engine operation tied to aging emission control components
• Failed emissions inspection from a faulty oxygen sensor
