Ok this has been pissing me off for quite some time now. I have a crx dx that has a d16z6 engine and ecu in it. My question is that I have my O2 sensor wired up right I think but I still get the code for it. I have researched as much as possable and I still come up with the same results. Some one told me which wires to connect them to. When I hooked One wire up to d14 my map sensor code would come on with my O2 code. Hook it back up, its fine with O2 code still on. The heating Code isn't on just the O2 code.
Can some one tell me that these are the right pinout codes for my 93 civic ex ecu. That would be THE BEST and would make my year so I can put my turbo on. Thanks. John

if this is an obd 1 car then are you using the 4 wire o2 with that ecu?

 

yep.
