hey guys i wanna how to install a A/F meter... i know it goes to the ox2 sensor but witch one or what cables ... help me out guys ...... i really appreciate it.
lemme see... i dunno if i can remember right off the top of my head. but i think i h ad a red, green, and purple. green went to the o2 sensor (ON THE PCM SIDE OF THE CLIP), the red goes to your interior fuse panel (i used radio fuse for ignition on), and the purple went to the lights. the gauge should have come with an instructions manual.
I was a retard, and now I'm permanently banned.
splice into the purple one on the ecm side
DRIVE HARD OR DONT DRIVE AT ALL!!!
be ready to see a pretty light show..... thats all a a/f ratio is for.... without wide band its useless...
Ok, sorry to steal the post, but on my Ecotec '04, I spliced into the purple wire, and got nothing. Does anyone have a wiring diagram for my car? Thanks.

it's most accurate at and only at WOT. but the range is voltage it reads is still very narrow compared to that of a wideband.

Could you explain that statement? A narrow band O2 sensor is only accurate
AT 14.7, and can tell you if you're above or below that point, but not by how much. At WOT you don't want to be anywhere near as lean as 14.7 (12.5-13.5 very generally speaking), so how is an A/F guage hooked up to a narrow band O2 sensor going to help you?
15.3 @ 89.97mph, 14's on the way?

well the red one goes to the ecm purple wire right ?

its actually very simple and shouldnt really need an explanation.
however...
what is ANY guage for?
to monitor something....everyone here can agree on that. it should be common knowledge.
have you ever heard of
DTC PO131 low voltage
DTC P0132 high voltage
and more specifically
DTC P0133
SLOW RESPONSE SENSOR 1
or DTC P0134 which is insufficient activity of sensor 1....
or even when your car has warmed up, winter or otherwise... from what some of you call a light show, is more or less a realtime view of how your first o2 sensor in constantly switching back and forth between lean and rich to try and keep things stoich.
those are just a FEW things that a narrow band o2 air fuel guage will monitor. you dont need a precise number for this...and if you dont have alot of mods, you dont need a wideband.....
the more power you add or the more mods you add to something, the more precision you need in the setup and monitoring. that goes for anything....engine, suspension, chassis, etc. the more you add the more precise you have to be. tolerances tighten with the more power and more handling you expect.
with that being said....theres plenty of people here who will never see forced induction nor have the need to run out and spend 3-400$ for a wide band o2 sensor... unless you simply want another set of numbers to impress the locals you hang out with who sweat people who have guages....
however WHEN...not if.... your o2 goes bad, or slows down, or if you run lean and you cant figure out whats going on with your car and why its running erratic, a narrow band o2 sensor can be a useful tool in helping you diagnose, and monitor how something is running when dealing with the first 02 sensor.
so i repeat, its only useless for those who are clueless how to use it....
Good enough, but it's still not of much use for tuning an engine to make power safely, which is why 90% of people who buy these wants them.

only thing is though, the people who are actually making power, know what to get... for the most part from what i;ve seen.
boosted, nitrous, extreme n/a setups. they know they need that extra precision.
however, theres alot of people that add gauges just to add guages. kinda like when you see people who never really autox, or road race, but they have the largest swaybars they can find
Muffins hit the nail on the head. People used to laugh at me for having an a/f gauge in my other car. I'd just turn around and laugh at them, because (generally speaking) I could instantly tell if something wasn't right, even before I could *feel* a difference in the way the car was driving.
Predict and prevent a future problem from occurring if you will.

S0o0 guys where do i connect the purple wire?
well if your 02 goes bad it throws a code, a narrowband is a worthless lightshow that isnt accurate at any time
1989 Turbo Trans Am #82, 2007 Cobalt SS G85
quote=Silver Streak]If I am at WOT in a 2200 should I be seeing the gauge reading all the way rich. I think I have head but to make sure the 2.2 s run pretty rich anyway but is this what I should see at Wot?
yes.

thats BS....
ask laura...
the past 2 weeks now i;ve been running lean. it showed on the a/f meter... no codes what so ever.
just today after checking the plugs, on my own mistake, two of the plugs were loose, hence letting combustion out. it showed on the plug boots from the soot.
would have never seen the problem if the a/f didnt start acting up.
and as i posted above:
"however WHEN...not if.... your o2 goes bad, or slows down, or if you run lean and you cant figure out whats going on with your car and why its running erratic, a narrow band o2 sensor can be a useful tool in helping you diagnose, and monitor how something is running when dealing with the first 02 sensor."
it doesnt always throw a code when things START to go wrong. when its gone wrong and doesnt work, then a code is thrown, and thats after 2-3 cycles... and the problem has to be constant.
alot of times a problem arrises, but goes away after warm up (my own problem with the spark plugs and my own fault) and also the time when the o2 started to slow down on the readings.
like said,
if you dont know how to read or use one, then and only then is it a "useless light show" as you put it....
before you post matt, know a bit about the subject. or as you like to say GET YOUR FACTS STRAIGHT
and yes, it is accurate if hooked up correctly in telling you the functionality of the o2 sensor. when its switching, and or setting at...
however its not accurate if you need to know exact air fuel ratio numbers such as 13.4, 15.0. etc....
even many of the a/f ratio meters available today in wide band come with the lights as well as the numbers...... its not just for show, only for the people who dont know how to read the red yellow green bars. very quick indicator of letting you know if the car is running rich or not... takes less time to glance at that than to focus on the exact numbers...
thats why both are on quite a few wideband sensors, matt.

DTC P0133 SLOW RESPONSE SENSOR 1 How do I fix this damn prolbem. I put in a new 02 sensor, and cleared the codes at autozone, and the light keeps coming back with this code.
do a search. there is a diagram on here somewhere that should of been a sticky

AS for the light show. It is pretty annoying and I plan to hook a switch or something under the dash and only turn it on whenever I plan on spraying to monitor the car.
Thanks Event

the two times i had that code one was my own fault, i didnt solder the connection (universal o2) , so it wasnt reading as accurate to the computer...
the second time i was given the wrong sensor. the older sensors for like 2nd and 1st gens reads, but tends to read slower and also can make you run lean.
did you get a direct replacement along with the connector, or did you have to cut and splice for a header, like with the pacesetters? or are you boosted already?
