well thank you i appreciate the help, now my other question is which wire would be the signal wire for the primary 02 sensor on a f23a4 engine, in the diagram it shows c16 on this site http://www.innovatemotorsports.com/r...nda_Accord.php, but i don't have a wire there and my engine is the ulev vtec, also this site gives me something different http://krcomp.com/pictures/ecu-pinout.pdf,

If your Accord is the ULEV, then it would have an air/fuel ratio sensor. I believe the signal (+) wire would be this one:

how come it still shows that there is a c16 pin and on my ecu there is none? also i connected my air fuel ratio guage and nothin happens it just reads rich could this be because of a bad 02 sensor or no cat?

The reason the service manual shows a C16 pin is because the service manual covers different engines for those Accord years. C16 is for the F23A1 or F23A5 engine, which has a normal heated oxygen sensor. Your's doesn't have that pin because your's a F23A4, which has a air/fuel ratio sensor.

ok so just leave it connected to the c14 pin out? and how come its just readying rich? could it be a bad 02 sensor or no cat?
