I have a p28 ecu in my integra, and I am wanting to catch the 02 wire at the ecu. anyone know which pin the o2 wire is on the ecu and the color code of the wire? any diagram or something to point out the counting of the pins would be huge.

also, does the wire color/ecu pin change from ls to gsr?

thanks

Its pin # d14 its a white wire with an orange stripe. If you hit the search button and type in ECU pinouts in the archieves you can find a diagram showing which one is d14.

Edit: Here I was bored and searched for you....

thanks for the help

also, i should see the voltage change on the dmm when i rev my motor. if it doesn't, does that mean my o2 sensor is bad, or would there be an engine check light on for that?

your o2 sensor only has a max reading of 1 volt. It varies from 0-1 V depending on what it sees and sends that little change to your ecm and it inturprets what to do. So no hooking up your dmm will not do much for you and yes there is a check engine fault code for a O2 sensor that isn't working.
