  • Emissions test failure tied to sensor output
  • Rough fuel control caused by degraded exhaust feedback
  • Corrosion or damage at the sensor body or connector

Installation Notes

Confirm the rear sensor location before installation and verify thread size, connector shape, and wire count against the original part. Inspect the exhaust bung threads and wiring routing during replacement, and follow the included instruction sheet for proper installation steps. Delphi ES20380 is specified for the rear position on the listed Honda CR-V applications.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and engineering knowledge developed through long-term supplier experience with leading automakers. That OE-based approach supports consistent fit and function for the Honda CR-V rear oxygen sensor application.
