Detailed Description

The Delphi ES20095 oxygen sensor is designed for vehicles that rely on accurate exhaust oxygen readings to manage fuel delivery and emissions control. Its heated design helps the sensor reach operating temperature quickly, which supports more consistent feedback during cold starts and normal driving. Delphi builds this part using OE experience gained from supplying major automakers, bringing factory-level application knowledge to the aftermarket replacement.

This part number is commonly used on vehicles such as the Chevrolet Silverado 1500, GMC Yukon, Cadillac CTS, and Chevrolet Camaro in the listed positions. It also cross-references Bosch 15896 and DENSO Auto Parts 234-4244 for the same application.

What It Helps Address

Check engine light related to oxygen sensor performance
Rough idle caused by inaccurate exhaust feedback
Fuel trim issues from a slow or aging sensor
Failed emissions inspection tied to sensor output problems
Reduced drivability from inconsistent air-fuel ratio control

Installation Notes and Tips

Verify the exact position before ordering, since this sensor is listed for front, front right, rear, and rear left locations depending on the vehicle. Confirm connector shape, thread size, and overall length against the original sensor before installation. For best results, compare the application tab with your vehicle’s engine and exhaust layout, especially on models such as the Cadillac CTS, Chevrolet Silverado 1500, and GMC Yukon.

Quality Assurance

Delphi draws on more than 100 years of OE experience and supplier knowledge used by top automakers. That OE background is built into this aftermarket oxygen sensor to support accurate fitment and dependable replacement performance.
