Questions about these listings
Which model years are named in the listings for Mazda Mazda3 oxygen sensors?
15 listing titles give model years from 2004 to 2016; 2010–2013 appears most often (3 listings). Check your car’s year against the fitment details in each listing.
Which positions are named in the listings for Mazda Mazda3 oxygen sensors?
The titles name downstream (11 listings) and upstream (11). 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 Mazda Mazda3 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 Mazda Mazda3 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.
