- Incorrect exhaust oxygen readings from a worn rear sensor
- Rough emissions monitoring on the rear right exhaust position
- Slow sensor response after startup
- Failed emissions inspection tied to sensor output issues
Installation Notes and Tips
Verify rear right placement before ordering, since fitment is position-specific. Confirm the connector shape, wire count, and thread size match the original sensor on your Hyundai Sonata, Hyundai Santa Fe, Hyundai Tiburon, or Kia Optima. Compare the existing sensor length and routing path to the 640.0 overall length listed for this part. Follow the included instruction sheet and use proper exhaust sensor service practices during installation.
Quality Assurance
Delphi builds this replacement oxygen sensor using OE-focused engineering and manufacturing knowledge developed through long-term supplier experience with leading automakers. That background supports consistent fitment and sensor construction for the listed rear right applications.
