Denso 234-4769 is an OE Style heated oxygen sensor built for direct replacement on select Dodge Ram, Jeep Grand Cherokee, Jeep TJ, and Jeep Wrangler applications. It is engineered for specific fitment, stable signal output, and accurate exhaust monitoring in upstream locations.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct replacement service
• 4-wire configuration with female connector
• Threaded mounting with 0.708 in. thread diameter
• 18.19 in. wiring harness length for OE-style routing
• OE Style construction for select upstream applications

Product Details

This Denso oxygen sensor is manufactured and tested to OE standards, with precision-built dimensions for first-time fitment. The sensor uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting consistent engine management performance and fuel control. Part number 234-4769 is a direct replacement choice for drivers servicing upstream sensor locations on 2001-2003 Jeep Grand Cherokee, 2001-2003 Jeep TJ, 2001-2003 Jeep Wrangler, and select 2001-2003 Dodge Ram 1500, Ram 2500, and Ram 3500 models.

This part cross-references Bosch 13687 and NTK 23139 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor faults
• Rough idle caused by inaccurate exhaust feedback
• Reduced fuel economy from poor air-fuel ratio control
• Slow sensor response during cold starts
• Emissions test failures tied to upstream sensor performance
