Questions about these listings

Which part numbers appear in more than one listing for Cadillac XT6 oxygen sensors?

12670253 appears in more than one title. Compare the number on your old part with the listing before you buy.

How do I check fitment before buying Cadillac XT6 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 Cadillac XT6 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.
