Denso 234-4092 Oxygen Sensor - Downstream, Downstream Rear or Upstream

Denso 234-4092 Oxygen Sensor Overview

Denso 234-4092 is a specific-fit heated oxygen sensor built for OE-style replacement in select Honda, Acura, and Isuzu applications. It is engineered for accurate exhaust feedback, stable engine management, and a first-time fit on the listed downstream and upstream positions.

Denso’s OE Style line focuses on direct replacement parts that match factory fit and function. This oxygen sensor uses a threaded mounting design, a female connector, 4 wires, and a 24.02-inch wiring harness for the specified applications.

Key Features

• Heated oxygen sensor for faster operating readiness
• Specific-fit design for direct replacement
• Threaded mounting type with 0.708-inch thread diameter
• Female connector with 4-wire configuration
• 24.02-inch wiring harness length
• OE Style construction for factory-style fit and function
• Built with Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination

Detailed Product Information

This Denso oxygen sensor is designed for vehicles that require precise exhaust monitoring to support fuel control and emissions system operation. It is a direct replacement for select 2001-2005 Honda Civic downstream applications, 1997-2001 Honda Prelude upstream and downstream applications, 1995-1999 Acura NSX downstream rear applications, 1996-1999 Isuzu Oasis downstream applications, and 1996-1998 Honda Odyssey downstream applications. The part number 234-4092 is also referenced across several OE and aftermarket cross numbers for the same application.

This part cross-references Bosch 13071 and NTK 24061 for the same application.

What This Oxygen Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a worn sensor
• Reduced fuel economy caused by slow or inaccurate exhaust feedback
• Emissions test failures tied to sensor response issues
• Driveability problems linked to degraded upstream or downstream sensor output

Installation Notes and Tips

Verify the sensor position before ordering, since this listing covers downstream, upstream, and downstream rear locations depending on the vehicle. Confirm connector style, wire count, and thread size against the original sensor before installation. For best results, inspect the harness routing and exhaust threads for damage or contamination before threading in the replacement sensor.

Quality Assurance

Denso manufactures and tests this OE Style oxygen sensor to strict original-equipment standards for fit and performance. The design emphasizes accurate replacement, stable operation, and protection of the sensing element for long service life.
