the upstream o2 sensor on my 06 3i has 5 wires. is this a wideband sensor? i know on my vw 1.8t the upstream was a bosh wideband and that had 5 wires, along with the aem wideband i have on my supercharged mustang also has 5 wires.

just curious, thanks.

it is pzev or federal emissions?

federal i beleive. i think the cali ones have 3 o2 sensors, one upstream, one downstream, and a 3rd after the 2nd cat. i only have 2 sensors so im guessing federal?

Nevermind

correct, with the 0-5v. i just never saw a 5 wire narrow band, only 1 wire, 3 wire, and 4 wire. all 5 wires that i have had experence with have been widebands, (on my vw, and the aem uego on my mustang)..... im waiting for a header to show up and figured id take a look to see how much room is back there and noticed the 5 wires. ill have to back probe it tomorrow to see what the voltage is, or scan it on monday and see what kind of readings im getting.

i know eairler 3's have a narrow band but i was thinking that maby they changed??????

anyways, thanks for the info.

After reading up on it, are you sure there are 5 wires? I am second guessing myself here since I have never seen a 5 wire narrowband either.

positive on the 5 wires on it. only my upstream one though, downstream has 4 wires. ill take a pic later today.

i tried to post a pic, only to find out i have no idea how to do it. Any help would be appreaciated.

colors on my upstream wire:

grey
white
black
blue
yellow

im thinking maby mazda switched to a wideband after a certin year for emissions reasions or something??? Or its a new type of a narrowband i have never seen before?

 

[boardumb]

I believe it is wideband now. Sorry for the misinformation. I've read some people have been reading their factory widebands with certain scan tools, and most if not all widebands i've seen were 5 wire.

awsome. thanks for the info.
