Detailed Description
Delphi ES20167 is an emission control sensor engineered for rear-position exhaust feedback on the Volvo S40 and Volvo V40 from 2000 through 2004. Delphi draws on OE heritage and more than 100 years of supplier experience, bringing factory-level design knowledge into this aftermarket oxygen sensor. The ES20167 part number is also a useful reference when sourcing the correct rear oxygen sensor for these Volvo models.
This part cross-references Bosch 16292 for the same application. It also interchanges with ES20167 reference numbers including 25603 and OS1657 for fitment verification.
What It Helps Address
- Check engine light related to rear oxygen sensor performance
- Incorrect exhaust oxygen readings from a worn sensor
- Fuel control issues caused by inaccurate sensor feedback
- Emission test failures tied to sensor degradation
- Slow or inconsistent sensor response in the rear exhaust stream
Installation Notes and Tips
Confirm rear-position fitment before ordering, since this sensor is specified for the rear location only. Verify the connector shape, wire count, and thread size against the original sensor on the vehicle. For 2000-2004 Volvo S40 rear oxygen sensor and 2000-2004 Volvo V40 rear oxygen sensor applications, compare the OE connector and harness routing before installation.
Quality Assurance
Delphi builds this oxygen sensor using OE experience and supplier knowledge developed across a century of automotive manufacturing. That background supports consistent fitment and sensor design for the specified Volvo rear applications.
