OE-Style Replacement Details
Delphi ES10937 is an emission control sensor engineered from decades of OE experience and supplier knowledge. The sensor is specified for front placement and matches the listed connector and thread configuration, making it a practical replacement for vehicles that need accurate air-fuel ratio or oxygen sensor service. This part cross-references DENSO Auto Parts (e.g., 234-9004, 234-9005) for the same application.
Compatible with 2001-2005 Honda Civic, front; 2005 Honda Civic, front; 2002-2004 Acura RSX, front; and 2002-2004 Honda CR-V, front. Search terms such as front oxygen sensor for 2001-2005 Honda Civic, Delphi ES10937 for Acura RSX front sensor replacement, and Honda CR-V front air-fuel ratio sensor replacement align with this application.
What This Sensor Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio readings at the front sensor location
- Emissions test failures tied to sensor response issues
- Rough idle or drivability concerns caused by faulty sensor feedback
- Fuel economy loss from inaccurate exhaust oxygen measurement
Installation Notes and Tips
Verify the front sensor location, connector shape, wire count, and thread size before installation. Compare the original sensor length and connector routing to the Delphi ES10937 to confirm proper fit on the vehicle. Follow the included instruction sheet and inspect the harness path to avoid strain or exhaust contact after installation.
Quality Assurance
Delphi builds this oxygen sensor using OE heritage and application knowledge developed through long-term supply relationships with major automakers. That background supports consistent fitment and sensor construction for the listed Honda and Acura front sensor applications.
