Detailed Description

Delphi ES20088 is engineered for vehicles that require a heated oxygen sensor with OE-style fitment and connector geometry. Delphi draws on more than a century of OE experience, and that background is reflected in the design and application coverage of this replacement sensor. This part cross-references Bosch (e.g., 13686, 15151) for the same application.

Use Delphi ES20088 when servicing emissions-related sensor faults on applications such as Chevrolet Colorado rear, GMC Canyon rear, and Buick Regal rear. It also covers additional GM platforms including Chevrolet Malibu, Hummer H3, Pontiac G6, Saturn Sky, and Chevrolet Silverado 1500 rear applications listed in the fitment data.

Common Issues This Sensor Can Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel feedback from a failing upstream or downstream sensor
  • Rough idle or drivability concerns tied to exhaust sensor signal loss
  • Emissions test failure caused by a degraded oxygen sensor
  • Connector or thread mismatch during replacement on listed GM applications

Installation Notes and Tips

Confirm the exact position before ordering, since this part is listed for front, rear, and rear right locations depending on the vehicle. Verify connector shape, wire count, and thread size against the original sensor before installation. For fitment-specific applications, use the vehicle’s application tab to match the correct side and position.
