Product Details
This Denso oxygen sensor is manufactured to OE-level standards and built for precise replacement in the exhaust stream. 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. It is a direct-fit emission control sensor for 2003 Dodge Dakota, 2003 Dodge Durango, and 2003 Dodge Ram 1500 applications, including downstream left and downstream right positions where listed.
This part cross-references Bosch 13687 and NTK 23556 for the same application. The Denso 234-4719 is a practical OE-style choice when replacing a worn downstream oxygen sensor on a 2003 Dodge Ram 1500, or on a 2003 Dodge Dakota or Durango with the listed position and notes.
Common Issues This Part Can Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio feedback from a failing downstream sensor
- Reduced fuel economy caused by inaccurate exhaust readings
- Emissions test failure tied to sensor response problems
- Rough or inconsistent engine management data from a degraded sensor
Installation Notes
Verify the connector style, wire count, thread diameter, and sensor position before installation. This is a specific-fit sensor for threaded mounting, so confirm the vehicle’s downstream left or downstream right location exactly matches the catalog listing. For 2003 Dodge Ram 1500, note the application distinction for California and non-California coverage shown in the fitment data.
Quality Assurance
Denso designs and tests this OE Style oxygen sensor to strict original-equipment standards for replacement accuracy and consistent operation. The construction focuses on first-time fit and long-term durability in demanding exhaust conditions.
