Detailed Description

Delphi ES20053 is an emission control oxygen sensor engineered for vehicles that require accurate air-fuel feedback from the exhaust stream. Delphi draws on OE heritage and decades of supplier experience to build aftermarket parts with the same application focus expected in original equipment service. This part cross-references Bosch 13007 and DENSO Auto Parts 234-4065 for the same application. It is a direct-fit option for select Honda Civic and Honda Accord models, as well as Acura NSX and Honda Civic del Sol listings shown below.

Compatible With 1996-2000 Honda Civic, front; 1997-2000 Honda Civic, rear; 1995-1999 Acura NSX, rear left; 1995-1997 Honda Accord, front; and additional Honda Civic and Civic del Sol applications with listed notes. For buyers searching for a Honda Civic oxygen sensor replacement or an Acura NSX rear left oxygen sensor, ES20053 matches the documented fitment data.

What It Helps Address

Check engine light concerns related to oxygen sensor performance
Incorrect air-fuel ratio readings from a worn sensor
Reduced exhaust feedback accuracy during closed-loop operation
Emissions test failures tied to sensor response issues
Driveability problems caused by delayed or unstable sensor output

Installation Notes and Tips

Verify the exact position before ordering, since this part is listed for front, rear, and rear left locations depending on the vehicle. Confirm the 4-wire square connector, 18 x 1.5 mm thread size, and overall length against the original sensor before installation. Review the application notes for California emissions and engine-code-specific coverage on certain 1993-1995 Honda Civic and Civic del Sol models.

Quality Assurance

Delphi builds this oxygen sensor using OE experience and application knowledge developed through service to major automakers. The included instruction sheet supports correct replacement procedures and fitment verification.
