hey guys, i took this pic to which i believe it's the oxygen sensor with the wires cut-off. can anyone confirm this and if it is, which are the wires to connect it to? the second pic is of the starter with wires sorta dangling.


thanks for the help

 

yes it is a very old burned to hell o2 sensor it hooks up to a connector on the rear passenger side of the engine

 

ok cool...is the connection more towards the engine bay or more behind it?

 

it should be coming off the back of the engine

 

That one looks like it's way farther back on the exhaust than mine. I've got an '86 N/A, and I can get to mine from the engine bay, just about even with the bell housing, passengers side. My connector is right above the bell housing, hard to plug and unplug, or to hook up a DVOM to check out your O2 Voltage readings.

 

That's an oxygen sensor alright. What it's doing back there is a better question though. They're supposed to be on the rear end of the exhaust manifold (NA) or on the precat (TII). Do you have headers? It may have been relocated in that case.

 

yes i do have headers. the thing is i need to replace the sensor so i can install my a/f ratio gauge but i cant seem to find the wires to connect the o2 sensor. i've checked the fsm but cant seem to find it there either. (sureshots link to the fsm)

 

If I am not mistaken, the O2 sensor wire is a shielded gray wire that comes out of the harness from around the primary injector area. It is shielded, so you need to make your connection to the INNER wire and not the braided shield.

 

ok...gonna check right now....

 

so i guess that means i may have to take off the uim to get to the wire? cuz the only thing i see is the pd, and the wire for the water thermo sensor (think thats it) i dont see a gray wire. would pics be better to see?

 

ok...dave (misterstx69) told me a location to where the o2 hooks up. when i checked (told me behind the tb near the lim) there was no wires or a plastic connector/wire anywhere. here are some pics for you guys to check it out.

 

disregard my pics cuz there wer nowhere near it. i did found a white connector with a single black wire. here's a few pics. so do you think this is it?

i know it's kinda hard to see but it's right on the tip of my finger.

 

The connector you are looking for is a pale green. The male and female ends, when connected, look similiar to an inline glass fuse connector, just a little shorter.

 

^^He's right. The O2 sensor wire connector is green, and the connector coming off the O2 sensor that connects to it is white, at least on my 88 SE. I actually just rewired mine today, for my RB header.

Aaron, regarding the shielded O2 sensor wire... I just soldered my old one onto it, twisting the wires around each other. Will it get a good signal that way?

 

ok..i'll check again but i'm beginning to believe it's been cut-off. thanks guys

 

mine broke off at the harness due to a nosey neighbor try to see how big the turbo and did say anything about, I just opened the harness and soldered the wire back in place
