Delphi ES20113 Oxygen Sensor Overview

Delphi ES20113 is a heated oxygen sensor built for direct-fit emission control service on a wide range of GM, Cadillac, Buick, Chevrolet, GMC, Pontiac, Saturn, Saab, Suzuki, and Isuzu applications. It combines OE heritage with the sensor specifications needed for accurate exhaust feedback and dependable engine management.

With a 4-wire heated design, square connector, and 18 x 1.5 mm thread size, this oxygen sensor is built for front or rear positions depending on the vehicle application. It is a practical replacement for drivers servicing a Cadillac CTS rear oxygen sensor, a Chevrolet Traverse front oxygen sensor, or a GMC Acadia rear oxygen sensor.

Key Features

Heated oxygen sensor design for faster operating temperature
4-wire configuration for common OE-style applications
Square connector shape for proper harness connection
18 x 1.5 mm thread size for direct mounting
Overall length: 310.0
Package includes oxygen sensor and instruction sheet
Fits front, rear, front left, front right, rear left, and rear right positions by application

Detailed Description

Delphi ES20113 is engineered from more than a century of OE experience and supplier knowledge built into aftermarket replacement parts. As an emission control oxygen sensor, it monitors exhaust oxygen content so the engine control system can adjust fuel delivery and maintain proper air-fuel balance. That makes it a strong service part for vehicles that need accurate sensor response after a fault code, drivability complaint, or emissions test failure.

This part cross-references Bosch 15894 and DENSO Auto Parts 234-4285 for the same application. It also matches a broad range of fitments including 2012-2017 Buick Enclave, 2012-2016 GMC Acadia, 2013-2019 Cadillac ATS, and 2012-2017 Chevrolet Traverse. Part number ES20113 is also listed across multiple interchange references for expanded catalog matching.

Common Issues This Sensor May Address

Check engine light related to oxygen sensor performance
Incorrect fuel trim readings from a worn exhaust sensor
Failed emissions inspection caused by sensor response issues
Rough idle or reduced fuel control from inaccurate exhaust feedback
Replacement needs after sensor contamination or age-related wear

Installation Notes and Tips

Verify the exact position before ordering, since ES20113 is used in front and rear locations depending on the vehicle. Confirm connector shape, thread size, and wire count against the original sensor before installation. For best results, compare the application tab with your vehicle’s year, make, model, and position, especially on vehicles such as the Chevrolet Camaro, Cadillac CTS, and GMC Acadia where multiple sensor locations may be used.

Use the included instruction sheet during installation and inspect the harness routing, connector lock, and exhaust bung threads before tightening the sensor.

Quality Assurance

Delphi builds this oxygen sensor using OE heritage and application knowledge developed through long-term supplier experience with major automakers. That background supports consistent fitment and sensor performance across the listed applications.

This part fits 217 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
