my check engine light is on and the code is for checking for the 2ndary O2 sensor. its code 21 I think. My car is a b16a in a crx. My shop tells me that it is wired up right, the wire is just loose (halfass install). What wire am i looking for to get it all tight? pictures or the ecu pinout would be nice. Do I need to give you all any other information? Im not sure what my ecu is, it would be the one that came with my b16a swap. JDM ecu I think!

 

Nobody with any comments? What are the 02 sensor input pin numbers? and how should it be wired for my b16?

 

did you convert to obd1 or is it obd 0 still? what ecu? look on the side of your ecu and it should have a bar code , read the bar code and it should be someting like 37820-pm8-a020(my old hf ecu).So from that bar code we know that my ecu is a Pm8.Good luck.

 

if you really have the jdm ecu check this out http://www.geocities.com/b16ap....html. Thats all i can think of.

 

that might actually be what i need. thanks man

 

Wasnt what I needed. I do believe I have a pr3 ecu with my b16a and its throwing code 21 or 22, what would those codes be?
