Denso 234-4768 Oxygen Sensor - Downstream Rear

Denso OE Style Oxygen Sensor 234-4768

Denso 234-4768 is an OE Style heated oxygen sensor built for direct replacement in specific Jeep applications. It is engineered for accurate exhaust feedback, stable engine management, and a first-time fit on the vehicles listed below.

Key Features

• Heated oxygen sensor for faster operating readiness
• Specific-fit design for direct replacement
• 4-wire configuration with female connector
• Threaded mounting type with 0.708 in. thread diameter
• 18.19 in. wiring harness length
• OE Style construction for factory-type fit and function
• Aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination

OE Style Construction

The Denso OE Style line is built to match original equipment requirements for fit, form, and function. This oxygen sensor is precision built for exact replacement, helping restore proper exhaust signal feedback on 2001-2004 Jeep Grand Cherokee, 2001-2004 Jeep TJ, and 2001-2004 Jeep Wrangler downstream rear applications. The Denso 234-4768 is designed for drivers replacing a worn sensor that can affect fuel control, emissions performance, and drivability.

This part cross-references Bosch 13687 and Standard Ignition SG1852 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture feedback from a failing downstream rear sensor
• Reduced fuel economy caused by inaccurate exhaust readings
• Emissions test failures tied to sensor response issues
• Rougher engine operation after sensor aging or contamination

Installation Notes

Fits 2001-2004 Jeep Grand Cherokee, downstream rear. Fits 2001-2004 Jeep TJ, downstream rear. Fits 2001-2004 Jeep Wrangler, downstream rear. Verify connector style, thread size, and harness routing before installation. Use the threaded mounting point and route the 18.19 in. harness away from heat sources and moving components. Confirm the replacement location is downstream rear before ordering the Denso 234-4768.

Quality Assurance

Denso manufactures and tests this sensor to OE standards for replacement accuracy and consistent performance. The sensor uses an aluminum oxide trap layer to help shield the ceramic element from silicone and lead poisoning, supporting long-term reliability in demanding exhaust environments.
