Detailed Description
Delphi ES20047 is engineered for emission control service where accurate oxygen sensing is critical to fuel control and catalyst efficiency. The heated design helps the sensor reach operating temperature quickly, supporting consistent exhaust feedback during cold starts and normal driving. Delphi’s OE background is reflected in the sensor’s construction and application coverage across multiple Chrysler, Dodge, Jeep, and Plymouth platforms. This part cross-references Bosch 13100 and DENSO Auto Parts 234-4005 for the same application.
Vehicle coverage includes 1996-2002 Dodge Viper, 1998-2001 Dodge Ram 1500, 2000-2001 Dodge Ram 3500, 2000-2001 Jeep Cherokee, 2000 Jeep Grand Cherokee, and 1997-1999 Jeep Wrangler. The Delphi ES20047 is also listed for additional Chrysler, Dodge, Jeep, and Plymouth models where the position and notes match the factory configuration.
What It Helps Address
- Check engine light concerns related to oxygen sensor performance
- Incorrect air-fuel mixture feedback from a worn sensor
- Slow sensor response during cold operation
- Emission control faults tied to front, rear, or right-side sensor locations
- Driveability issues caused by inaccurate exhaust oxygen readings
Installation Notes and Tips
Verify the exact position before ordering, since this part is listed for front, front right, rear, and right locations depending on the vehicle. Confirm thread size, connector shape, wire count, and harness length against the original sensor before installation. For fitment examples, this part fits 1998-2001 Dodge Ram 1500, front; fits 2000-2001 Jeep Cherokee, front; and fits 1999 Jeep Grand Cherokee, rear with 18in pigtail. Use the vehicle application tab to match the correct side and emissions configuration, including California-emissions-specific listings where noted.
Quality Assurance
Delphi builds this oxygen sensor using OE experience and supplier knowledge developed over more than a century of original-equipment service. That OE heritage is applied to aftermarket replacement parts to support proper fitment and dependable emission-system operation.
