Questions about these listings
Which model years are named in the listings for Cadillac CTS oxygen sensors?
11 listing titles give model years from 2004 to 2017. Check your carβs year against the fitment details in each listing.

Which part numbers appear in more than one listing for Cadillac CTS oxygen sensors?
12594935 and 12596327 appear 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 CTS 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 CTS 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.
