Detailed Description

Delphi ES10677 is an emission control oxygen sensor for front placement in select 1991-1994 Dodge Colt and Mitsubishi Expo, Expo LRV, Galant, and Mirage applications. It is engineered with a non-heated sensing element and a 2-wire configuration, making it a direct-fit option for vehicles that use this connector and thread specification. The ES10677 part number is also referenced in aftermarket catalogs for the same application, including DENSO 234-2066 and Walker Products 250-22066.

Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers, and that background is reflected in the design and application matching of ES10677. For buyers searching for a front oxygen sensor for a 1993 Mitsubishi Galant from 06/1992, or a replacement oxygen sensor for a 1991-1992 Mitsubishi Mirage, this part number is a focused match to the listed fitment.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback from a worn front sensor
• Rough idle or drivability issues tied to exhaust sensor signal loss
• Failed emissions inspection caused by a degraded sensor
• Slow or inaccurate sensor response in the exhaust stream

Installation Notes and Tips

Confirm the vehicle uses the listed front-position application, thread size, connector shape, and non-heated 2-wire configuration before installation. This ES10677 oxygen sensor is specified for vehicles without California Emission System coverage where noted, so match the emissions setup carefully. Compare the original connector and sensor length to the replacement part before final installation.

Quality Assurance

Delphi builds aftermarket parts using OE experience and supplier knowledge developed through work with major automakers. The ES10677 is supported by that OE heritage and is supplied with an instruction sheet for installation reference.
