Denso OE Style Oxygen Sensor 234-4368

Denso 234-4368 is an OE Style heated oxygen sensor built for direct replacement on select Honda and Acura applications. It is engineered for a specific fit, threaded mounting, and a 4-wire male connector to match the original sensor layout on the vehicle.

The OE Style line focuses on exact replacement fitment and factory-style performance. Denso uses precision-built components and an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine operation and consistent fuel control.

Key Features

  • Heated oxygen sensor for faster operating response
  • Specific fit design for direct replacement applications
  • 4-wire configuration with male connector
  • Threaded mounting type with 0.708 in. thread diameter
  • Wiring harness length: 21.26 in.
  • OE Style construction for factory-style fit and function
  • Part number: 234-4368

Detailed Description

This Denso oxygen sensor is designed for downstream and upstream positions depending on the vehicle application, including Honda Odyssey, Honda Pilot, Honda Ridgeline, Honda Accord, Acura RL, Acura MDX, Acura TL, and Honda S2000 coverage listed below. For shoppers searching for a Honda Accord downstream oxygen sensor, Acura MDX downstream rear oxygen sensor, or Honda Odyssey OE style replacement, 234-4368 provides the correct sensor format for the specified applications. This part cross-references Bosch 13184 and NTK 24249 for the same application.

Denso’s OE Style product line is built around exact replacement requirements, so the sensor matches the original mounting style and electrical connection expected by the vehicle. The protective trap layer is intended to help reduce contamination-related wear, which supports more consistent emissions-system operation and fuel management over time.

What It Helps Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel ratio readings from a worn sensor
  • Reduced fuel economy caused by slow sensor response
  • Emissions test failures tied to sensor degradation
  • Rough engine operation from inaccurate exhaust feedback

Installation Notes and Tips

Verify the sensor position before ordering, since this part is listed for upstream, downstream, downstream front, and downstream rear applications depending on the vehicle. Confirm the connector style, wire count, and threaded mounting dimensions against the original sensor before installation. For fitment searches, this part is listed for 2001-2002 Acura MDX upstream, 2003-2006 Acura MDX downstream rear, 2004-2006 Acura TL downstream front and downstream rear, 2003-2007 Honda Accord downstream and downstream rear, 2005-2010 Honda Odyssey downstream rear, 2005-2008 Honda Pilot downstream rear, 2006-2008 Honda Ridgeline downstream rear, and 2004-2005 Honda S2000 upstream.
