I've been looking for a site like this for some time now.
Currently I love my 02 Accord EX and I've been doing some modifications in hopes of some day using petroleum alternative fuel like HHO.
Now I've been reading up on 02 sensors as an effective way to correct "Check Engine Light" problems for other modifications.
I'd love if somebody had clear diagrams or pictures on where the O2 sensors are located on the 2002 Accord EX.
I hope to share my results with all of you if you are interested.
Thanks for your help.
