air feul ratio gauge

[GOR33]

hey peeps

ive just done a few searches and i cant find the info im after, so i thought id ask.

im trying to hook up my air fuel gauge and i dont know which is the signal wire on the o2 sensor. the autometer instructions say i have to splice the wire after the clamp thing but is that nessecary? the wire that i spliced after the clamp adapter thing is a thick wire with copper colour wire in the middle, silver wire around it then the clear sort of heat shrink around it. is this the right wire?

if anyone can give me any hints id appreciate it heaps!!!!

[GOR33]

anyone, cum om peoples i need help, i cut up my o2 sensor leads and cant drive my car till i work out wats goin on:(

[GOR33]

P.s

I Cant Spell Good.............haha

Hi i fitted one of those to my car but it got stolen with the rest of my gauges anyway the wire i had it joint to was the middle wire on the plug it was a brown wire if you peel back the black stuff that covers the wires it should be a bit thicker than the other two (not the wires on the sensor) hope that helps

[GOR33]

yep sic thats the wire i am trying to use, but it has like 2 different colour wires on the inside, like silver and copper, so i just join it to both then hey?

also does the gauge actuall start to work right away or does the car have to heat up 1st, casue ive hooked it all up and the gauge didnt work???

thanks for the help jason

[jay.r33]

i joint it to the thinner part of that wire not sure if it makes any difference but it still worked as for the gauge it should work as soon as you start the car just check your other connections make sure there all connected properly let me know how you go

[GOR33]

ok sweet, i bought the gauge second hand off the net, so maybe it doesnt work?? are these things something that brake or not? oh well ill go out now and fiddle with it, ill be back.........thanks heaps mate

[jay.r33]

not sure what there like with breaking i got mine new and only had it for about a month then my car got broken into good luck hope it works

[GOR33]

just one last question- i have plugged everything in, and when its just the + and - wire in, there is a green led lit on the last point closest to the end of the rich section. then when i plug in the o2 sensor wire the screen goes blank, even wen the car is on. do i have to be driving for the thing to work or have i done sumthin wrong?

[GOR33]

is anyone awake yet? heeeellllllpppp mmmeee! im a bumbass:)

[Abo Bob]

Green sounds good.

[GOR33]

yeh but thats wat happenes wen the o2 sensor isnt plugged in, once i plug that wire in there is nuthin on the screen. as im turning on the car all the lights sorta flash but then it idles and theres nuthin????

[Mr GTS4]

there should be a RED - WHITE - BLACK wires coming out of the plug.. the white on is the signal wire.

[GOR33]

haha, i have a thin brown, thin light blue and thick brown wire set up, i was told the thick brown wire

man i dont know wats goin on, any more help would be great guys:)

[GOR33]

heellllloooooo sumones gota be there

[GOR33]

oh my god i think its kinds working now

[Wogboy]

When I fitted mine, I attached it to the white signal wire from the ECM (save trying to get out of the cab). Can't remember the pin # right now.

[GOR33]

ok i got it all hooked up now, but wats it supposed to look like, about 4 leds light up at a time going up and down the face wen u rev it and on idle sumtimes, it just hits rich. but at night wen i turn the lights on, it read a couple of leds short, is this supposed to happen?

let me know if u think it is functioninf wrong.......thanks for the help so far:)

[rs73]

which gauge is this? got any pics to show us?

[fresh]

i tihnk there should only be one led on at a time, considering its measuring a ratio, not a range of ratios, the led will move rapidly though

the gauge should work alll the time, driving idling, warming up etc.... i believe the oxy sensor doesn't work effectively till its warm and hence the ecu ignores the signal from it when u cold start, but once warm u should get semi accurate readings regardless of wheter u r drivign / idling / just starting
