How many 02 sensors?

[Tbuck07]

I'm pretty sure I already know the answer to this..but theres an o2 sensor on the exhaust piping on both passenger and driver side right? Im still baffled I cant find the harness for the driver side o2..THeres a bung for an 02 in the exhaust and looks like one had been broken off in it but I cant tell. Just making sure theres two o2 sensors and not just one.

Yeah we have 2 O2 sensors. So your saying you can't find the wiring that would normally connect to the Driver side O2??

 

[Tbuck07]

Yep. I found something that looks like its in the wire loom to the transmission..but it doesnt look like the other side's wire plug to fit onto the o2.

What kinda MPG you getting ???

 

[Tbuck07]

Dont know. I know the cars running like crappeh. Ive been running on one o2 sensor ever since I got the car..maybe thats why my check engine light is on..

 

[Win]

Yeah that would explain it.

 

[Tbuck07]

So if I cant find the harness at all what steps would I have to take to get that o2 plugged in?

I think the o2 wires come out of the harness near the oil pan.

Sounds correct. When i am under my car over the next few days if i can remember to look i'll let you know exactly where they are on a 94. I would assume they would be in almost the same position for a Fox Body

i believe it splits off at about the oil pan. trace your passanger side one back and you should come to were it splits off might of got ripped off some how

 

[Tbuck07]

So my question is IF it did get ripped off..what do I do??

first- find the wire ends.
Cheap way- go to a salvage yard and cut a replacement from another car and splice into your wires.
Slightly more expensive- get a new o2 sensor extension (like the guys with long tube headers need), and cut off the end you don't need. Splice into you wiring.

I don't know if the v6 and v8 o2 sensor plugs are the same or if the 5.0 and 4.6 o2 sensor plugs are the same either. So to be on the safe side just get one from a 5.0 car.
