Detailed Description

Delphi ES10964 is an emission control oxygen sensor for front-position service on 1985-1987 Honda Civic models. Delphi draws on OE experience and supplier knowledge developed through work with major automakers, and that background is reflected in the sensor design and application coverage. This part cross-references Bosch 12050 for the same application. The Delphi ES10964 also aligns with common replacement searches for a front oxygen sensor for 1985 Honda Civic, 1986 Honda Civic, and 1987 Honda Civic.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback at the front sensor location
• Rough idle or drivability issues tied to exhaust sensor input
• Failed emissions inspection caused by a worn sensor
• Replacement needs for an aging Honda Civic front oxygen sensor

Installation Notes and Tips

Verify the 18 x 1.5 mm thread size, round connector shape, and 630 mm overall length before installation. This sensor is specified for front-position use on 1985-1987 Honda Civic models. Compare the existing connector and harness routing to confirm the single-wire, non-heated configuration matches the vehicle.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and application knowledge developed from supplying top automakers. That engineering background supports consistent fitment and serviceability for the ES10964 oxygen sensor.
