Delphi ES20007 Oxygen Sensor Overview
Delphi ES20007 is a heated oxygen sensor built for emission control service on a wide range of GM vehicles. It uses OE-based engineering from Delphi’s long history supplying automakers, with the fitment and connector details needed for direct replacement work on front or rear sensor locations.
Compatible with applications such as Chevrolet Malibu, Chevrolet Impala, Buick Lucerne, Pontiac G6, and Saturn Vue, this oxygen sensor supports accurate exhaust feedback for vehicles across the 2004-2013 model years. The Delphi ES20007 is a practical choice when replacing a worn sensor on a Chevrolet Malibu or Pontiac G6 with the correct OE-style configuration.

Detailed Description
The Delphi ES20007 oxygen sensor is engineered for vehicles that rely on precise exhaust monitoring to manage fuel delivery and emissions performance. Its heated design helps the sensor reach operating temperature quickly, which is important for consistent signal response during cold starts and normal driving. With a 4-wire layout, square connector, and 18 x 1.5 mm thread, this part is built to match the configuration used on many GM platforms.
This part cross-references Bosch 15152 for the same application. It also cross-references DENSO Auto Parts 234-4342 for the same application. For fitment-specific service, verify the position listed for your vehicle before installation.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Rough idle or inconsistent air-fuel feedback
- Reduced fuel economy caused by inaccurate exhaust readings
- Emission test failures tied to sensor response issues
- Slow sensor warm-up after startup
Installation Notes and Tips
Confirm the correct front or rear position for your vehicle before ordering or installing. Review the application tab for exact placement on Chevrolet Malibu, Chevrolet Impala, Buick Lucerne, Pontiac G6, and Saturn Vue models. Inspect the connector shape, wire count, and thread size against the original sensor to ensure proper fit. Follow the included instruction sheet and use the vehicle service procedure for sensor removal and torque specifications.
Quality Assurance
Delphi builds on more than a century of OE experience and supplier knowledge used by major automakers. That OE heritage is reflected in the ES20007’s design, materials, and application-specific fitment support.
