Detailed Description
Delphi ES20163 is an OE-style rear oxygen sensor engineered from Delphi’s long history supplying original equipment to major automakers. It is specified as a heated sensor with a flat connector and 4-wire configuration, making it a direct replacement choice for emissions service on the rear bank of the exhaust system. This part cross-references Bosch 16173 and DENSO Auto Parts 234-4864 for the same application. For drivers servicing a Volvo S60, Volvo XC70, or Saab 9-5, the ES20163 helps restore proper exhaust feedback after sensor wear or contamination.
What It Helps Address
- Check engine light related to rear oxygen sensor performance
- Incorrect exhaust oxygen readings from a worn sensor
- Emissions test failures tied to sensor response issues
- Rough fuel control caused by inaccurate feedback data
- Service replacement for aging rear O2 sensors on listed Volvo and Saab models
Installation Notes and Tips
