Gauges

Topic pretty much says at all where to I find the factory fuel sensor and what do I connect to once I find it?

I did a search of the forums I could not find the info I wanted so sorry if if has been covered before

Cheers

Jim.

Ok your not looking for a fuel sensor wire, your actually looking for the wire the PCM reads the air fuel ratios from, which runs of the EGO (o2 sensor). Do a search for that and you might have some more luck. I recall it was a white wire from memory, I could be wrong though

Ok yeah that's what I ment to say but I have no idea where I would even find that wire

can someone pin point it for me

EDIT: ok so its someplace around the inlet manifold is that right?

Look for the black wire on the sensor and either splice into that one or the grey wire on the other side of the black wire....if that makes sense to you

[Fat-Tony]

Just had a look at the wiring diagrams, Its a 4 wire heated sensor, you will find that it should have a black wire to ground the heating element, a P that goes into the heating element, and GR* which is the wire that goes into the ecu you want to splice. From the post above I assume that GR* means grey and a grey wire with a red stripe if I am not mistaken

Just thinking but wont a AFR gauge be pretty much useless because the factor oxy sensor it's only a narrow band, and to get the proper use from a AFR gauge you need a wide band Oxy sensor welded into your exhaust...

Yeh I'm starting to think that now after getting it oh well its a funky disco light untill I replace it with something alittle more functional

Or you could buy a wide band sensor, but that'l' set you baock at least $350.

With the stock narrow band sensor it's pretty much either ON or OFF at the switching point (correct me if I'm wrong) of an AFR of about 14.7

Not quite. Wide band sensors have come down in price of late. Now the AFR gauge with a narrow band sensor will be most accurate when around the 14.64 range (1 lambda) but as it moves from this AFR point its accuracy becomes diminished. None the less it will still retain some accuracy as to tell you if the car is running lean or rich but the further you vary from 1 lambda the less accurate it will be. Still would come in handy if you saw lean on the gauge when you were a WOT.

I still need to get off my ass and install all 3 anyway I have everything I need I jsut can't seem to find the time and still I have no idea on the afr
