Detailed Description
Delphi ES20208 is an emission control oxygen sensor engineered with Delphi’s OE heritage and decades of supplier experience. It is built for rear oxygen sensor locations on applications such as Dodge Ram 1500, Dodge Dakota, Dodge Durango, Jeep Liberty, and Jeep Wrangler, including select California Emission System vehicles. This part cross-references Bosch 15506 for the same application.
Use Delphi ES20208 when replacing a worn rear O2 sensor that is affecting exhaust feedback on 2001-2006 Dodge and Jeep platforms. The heated design helps the sensor reach operating temperature quickly, while the 4-wire layout supports accurate signal monitoring in the exhaust stream. For vehicle-specific placement, confirm whether your application calls for rear or rear-right installation.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel feedback from a failing rear sensor
- Emissions test failures tied to sensor response issues
- Rough idle or drivability concerns caused by inaccurate exhaust readings
- Replacement needs for damaged or aged rear oxygen sensors
Installation Notes and Tips
Verify the connector shape, wire count, thread size, and sensor position before installation. This part is listed for rear and rear-right locations; confirm the exact position for your Dodge Ram 1500, Dodge Dakota, Dodge Durango, Jeep Liberty, or Jeep Wrangler using the application details for your vehicle. Inspect the exhaust bung and wiring routing before tightening the sensor to specification.
Quality Assurance
Delphi builds aftermarket parts using OE experience and knowledge developed through long-term supplier relationships with major automakers. ES20208 reflects that OE-based approach in a replacement oxygen sensor for emission control service.
