So my upstream sensor has gone out and my engine is being flooded by gas. Im told the upstream is bad and looking for a replacement found a good deal on ebay but the description is for an 05 2.2 does anyone know if the upstream O2 sensors are different for the AP1 and AP2?

 

Make sure its a 4 wire, i dont think honda would of changed the sensors on different years. They are all narrow bands anyways so i think they are all identical, but double check from honda dealer to make sure.

 

the denso sensor they have listed for the 04 s2k does not match the part number listed by denso for the s2k so im deciding against it but i did find a walker sensor with matching part number for a good price that i may go with
