Delphi ES10179 Oxygen Sensor

Delphi ES10179 Oxygen Sensor Overview

The Delphi ES10179 is a non-heated upstream oxygen sensor built for older Chrysler, Dodge, and Plymouth applications. It uses a single-wire design with a round connector and 18 x 1.5 mm thread size, making it a direct replacement for select emission-control systems that rely on an upstream sensor signal.

Backed by Delphi’s OE heritage and decades of supplier experience, this oxygen sensor is built with the same application knowledge used in original equipment development. It is a practical choice for restoring accurate exhaust feedback on vehicles such as the Chrysler Fifth Avenue, Dodge Caravan, and Plymouth Voyager.

Detailed Description

The Delphi ES10179 oxygen sensor is engineered for emission control service on compatible Chrysler, Dodge, and Plymouth vehicles from 1985 through 1989. It is a direct-fit upstream sensor for applications including the 1985-1989 Chrysler Fifth Avenue, 1985-1987 Dodge Caravan, and 1985-1987 Plymouth Voyager, along with additional Dodge and Chrysler models listed in the fitment data. This part cross-references DENSO Auto Parts 234-1002 for the same application.

As an upstream oxygen sensor, ES10179 monitors exhaust oxygen content before the catalytic converter so the engine management system can respond to air-fuel mixture changes. Delphi’s OE background helps ensure the sensor matches the original application requirements for older fuel-injected and emission-controlled vehicles.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings from the upstream sensor circuit
• Rough idle or drivability issues tied to exhaust feedback errors
• Failed emissions inspection caused by sensor-related faults
• Slow or inaccurate sensor response on aging emission systems

Installation Notes and Tips

Verify the vehicle’s original sensor style, thread size, and connector shape before installation. This ES10179 uses a non-heated, one-wire design and is specified for upstream placement, so it should be matched to the correct location on the exhaust system. Inspect the harness, connector, and exhaust bung threads before installing the new sensor.

For best results, compare the removed sensor to the replacement part and confirm fitment for your exact year, make, and model. Compatible applications include 1985-1989 Chrysler Fifth Avenue, 1985-1987 Dodge Caravan, and 1985-1987 Plymouth Voyager, along with other listed Chrysler and Dodge passenger and van models.

Quality Assurance

Delphi draws on 100 years of OE experience and supplier knowledge from original equipment development. That OE heritage is built into the ES10179 oxygen sensor to support consistent fit and function in the specified applications.
