Questions about these listings

Which model years are named in the listings for Buick Regal oxygen sensors?

6 listing titles give model years from 2010 to 2020. Check your car’s year against the fitment details in each listing.

Which positions are named in the listings for Buick Regal oxygen sensors?

The titles name downstream (5 listings) and upstream (5). Order for the position on your car, as stated in the title or the seller’s fitment details.

How do I check fitment before buying Buick Regal oxygen sensors?

Find which sensor has failed. Upstream sensors sit before the catalytic converter and control fuelling; downstream sensors sit after it and monitor the converter. A fault code that names the bank and sensor number identifies the position. Some engines use a wideband (air-fuel ratio) sensor upstream. It is not interchangeable with an ordinary oxygen sensor, so match the type as well as the position.

Check compatibility before buying

These listings were found using Buick Regal oxygen sensors search terms. A search match does not establish fitment. Compare the part number, vehicle year, generation and engine with the seller's compatibility details. Confirm delivery, returns and the final price on eBay before ordering.

Match the oxygen sensor to its exact position

  • Find which sensor has failed. Upstream sensors sit before the catalytic converter and control fuelling; downstream sensors sit after it and monitor the converter. A fault code that names the bank and sensor number identifies the position.
  • Some engines use a wideband (air-fuel ratio) sensor upstream. It is not interchangeable with an ordinary oxygen sensor, so match the type as well as the position.
  • Compare the part number, connector and wire length with your old sensor or a sensor catalogue. A listing that names several models, or a 4-sensor kit, may not match the sensor you need.

Reference: NTK guide to oxygen (lambda) sensor types. Use the catalogue’s correct regional application.
