I need to know what color is what on the 5 wire primary o2 sensor for my HX. I could also use the ECU pinout for each wire too, but I most importantly need the wire color / function.

 

i just found this for a VX, but I have different colors. I have a blue wire... the pinout is different on the ECU because im obd2, but if the colors are the same, thats all i need.

NGK wideband O2 sensor VX ECU (OBD1)

orange - heater control (A6)
yellow - heater ground (thermostat ground)
white - O2 signal 2 (D14)
black - O2 signal reference (D16)
red - O2 signal 1 (D8)

thanks!

where did you find that?

 

NP. I found it in the 96-00 Civic Helms ETM sitting on my bookshelf.

 

thanks again!

i would also like to know what fuse the o2 sensor heaters are tied too.

TIA!

 

Alternator SP fuse (15A) in the under-dash fuse box.

 

all of my fuses are good, but i have no power coming out of A5/A6 for my o2 sensor heaters.

maybe something wrong inside the ECU?
