i have had my air fuel gauge hooked directly to my O2 sensor (white wire) and it was working fine and now it doesnt work anymore. i changed to a new o2 sensor and satill the air fuel gauge doesnt work. so i am going to try tapping the ECU but ther are 2 different o2 sensor wires on teh ecu. one wire is at A6 (orange/black)and it says it is o2 sensor heating element. and the other place is D14 (white/red) and that says just o2 sensor. i dont know which one to tap. any help?

it might be the A/F meter. unless some othere wire came loose, like a ground or something. since technically you are tapping the same wire, whether it be at the sensor or at the ecu.

well i thought that too but i also have my apexi turbo timer
(has airfuel on it as well) wired with the autometer one and it is not reading the o2sensor as well. i dont know why both of them would not be working. at least one of them should be working.

is there some kind of fuse or something?

Nextelbuddy

nope. i need to start off by eleiminating one or the other by wiring to the correct wire on the ecu. ill start off with the apexi first cuz i know that has to be good then the autometer.

just try that then take the autometer gauge out it see if the apexi works. and then try it with just the autometer gauge. or just find a friend with a civic (we all have friends with one.) and try it on that car.
