Detailed Description

Delphi ES20061 is an emission control sensor engineered for front exhaust placement on the listed Dodge Dakota, Dodge Durango, and Jeep Grand Cherokee applications. Delphi draws on OE heritage and supplier experience with major automakers, bringing that background into aftermarket replacement parts. This oxygen sensor is specified with a heated element, 4-wire layout, round connector shape, and 18 x 1.5 mm thread size for the correct fit where the vehicle calls for this configuration.

This part cross-references Bosch 13132 and DENSO Auto Parts 234-4634 for the same application. The Delphi ES20061 part number is also useful when searching for a front oxygen sensor for 2000 Dodge Dakota, 2000 Dodge Durango, or 1999-2000 Jeep Grand Cherokee without California Emission System.

What It Is Used For

• Replacing a failed front oxygen sensor
• Addressing check engine light concerns tied to oxygen sensor performance
• Restoring exhaust feedback for fuel control calculations
• Correcting drivability issues related to inaccurate air-fuel readings
• Resolving emissions test failures caused by sensor faults

Installation Notes and Tips

Verify the front sensor location, connector style, thread size, and vehicle emission package before installation. Compare the removed sensor to Delphi ES20061 to confirm the 4-wire round connector and overall length match the original part. Use proper exhaust sensor removal practices on a cool exhaust system and inspect the harness routing after installation.

Quality Assurance

Delphi builds this replacement part from more than a century of OE experience and supplier knowledge developed with leading automakers. That OE background is reflected in the sensor design and application-specific fitment for the listed vehicles.
