Delphi ES20028 Oxygen Sensor for Front Applications
The Delphi ES20028 is a heated oxygen sensor built for front sensor locations on select Chevrolet and GMC trucks, vans, and SUVs. It uses a 4-wire design, flat connector shape, and 18 x 1.5 mm thread size for direct-fit replacement where the original sensor matches these specifications.
Key Features
- Heated oxygen sensor for faster operating temperature and stable signal output
- 4-wire configuration with flat connector shape
- 18 x 1.5 mm thread size
- 375.0 overall length for listed front applications
- Includes oxygen sensor and instruction sheet
- Delphi part number ES20028
Detailed Description
Delphi builds this oxygen sensor using OE experience developed over decades of supplying original equipment to major automakers. The ES20028 is specified for front placement and is listed for a wide range of Chevrolet Express 2500, Chevrolet Tahoe, GMC Savana 3500, and GMC Yukon applications, along with other front sensor fitments across the 1990-2002 model years. This part number, ES20028, is also cross-referenced to Bosch 13027 and DENSO Auto Parts 234-4019 for the same application.
Compatible vehicle coverage includes front sensor service on Chevrolet C1500, K1500, Silverado 2500, Suburban 2500, and GMC C1500, K1500, Sierra 2500, and Yukon models where the listed length and connector style match the original setup.
What It Helps Resolve
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio readings from a worn front sensor
- Slow sensor response during closed-loop operation
- Rough idle or drivability issues tied to exhaust feedback faults
- Failed emissions testing caused by a degraded upstream sensor
Installation Notes and Tips
Verify the front sensor position, 375 mm overall length, 4-wire layout, and 18 x 1.5 mm thread size before installation.
