Denso 234-4064 Oxygen Sensor - Downstream Left, Downstream Rear or Downstream Right

Denso OE Style Oxygen Sensor 234-4064

Denso 234-4064 is an OE Style heated oxygen sensor built for specific-fit replacement on select Lexus and Toyota applications. It is engineered for downstream monitoring, with a threaded mounting design and a 4-wire male connector for direct-fit service.

Key Features

• Heated oxygen sensor for downstream exhaust monitoring
• Specific fit design for exact replacement on listed vehicles
• 4-wire configuration with male connector
• Threaded mounting type with 0.708 in. thread diameter
• 12.80 in. wiring harness length
• OE Style construction for factory-style fit and function

Product Details

Denso 234-4064 is manufactured and tested to OE standards for precise fitment and consistent sensor performance. The sensor uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine management and accurate exhaust feedback. This OE Style oxygen sensor is a direct replacement choice for downstream right, downstream rear, and downstream left positions on select Lexus ES350, ES330, ES300, GX460, and Toyota Avalon, Camry, and Solara applications. This part cross-references Bosch 15487 and NTK 24560 for the same application.

Vehicle Fitment

• Fits 2007-2014 Lexus ES350, downstream right.
• Fits 2006-2014 Toyota Avalon, downstream right.
• Fits 2007-2014 Toyota Camry, downstream right.
• Fits 2010-2013 Lexus GX460, downstream right.
• Fits 2004-2008 Toyota Solara, downstream rear.
• Fits 2004-2006 Lexus ES330, downstream rear.
• Fits 2002-2006 Toyota Camry, downstream rear.
• Fits 2005 Toyota Avalon, downstream left.
• Fits 2002-2003 Lexus ES300, downstream rear.

Common Replacement Uses

• Restores oxygen sensor signal accuracy after sensor aging or contamination
• Addresses check engine light concerns related to downstream sensor performance
• Supports proper air-fuel management and emissions monitoring
• Replaces a damaged or corroded threaded sensor assembly
• Helps correct drivability issues tied to faulty exhaust feedback

Installation Notes

Confirm the sensor position before ordering, since this part is specific to downstream right, downstream rear, and downstream left applications listed above. Match the connector style, wire count, and thread size to the original sensor, and inspect the exhaust bung threads before installation. For best results, verify vehicle year, make, model, and engine application against the fitment list for Lexus ES350, Toyota Camry, and Toyota Avalon coverage.

Quality Assurance

Denso builds this OE Style oxygen sensor to strict original-equipment standards and tests each unit for replacement accuracy and first-time fit. The design focuses on reliable sensor response, contamination resistance, and consistent performance in the listed Toyota and Lexus applications.
