The O2 sensor is plugged into the header but I simply can't find a plug that comes from the harness that will match up. The car is a 96 CX with a p28 and a jumper harness. Right now i'm doing about 16 MPG and guessing that this is the culprit. How can I find the plug from the harness? The O2 sensor that is bolted up to the header is a 4 wire o2 sensor. Also, there is 1 cable that is a 2 wire (green and black) that is coming from the harness but it is cut. and another clip but it looks like a 3 pin. Any help would be greatly appreciated, my gas mileage is really suffering.

 

Any check engine lights?

 

yes, and terrible mpg

 

did it have a d16y7 in it ? if so there should be a 4 wire plug in the harness near the dizzy

 

I've looked over an under the car and now next to the dizzy and still nothing. Any idea what color the cables are on the female?

 

just a sec i'll go look

 

beigh black yellow stripe, black white stripe, green white stripe is with the temp sensor and that other sensor right below the dizzy also the harness for the rear o2 runs down the tranny ummm do you need anything to post pic's i could take one for you .

 

Please I would greatly appreciate it, basically where the female o2 connects to the male primary sensor. I'm hoping they didn't cut the plug.

 

ok i have to go to work . i'll take a pic when i get home and try and post it

 

hope this works and helps .ok this won't upload pm me your e-mail and i'll send the pics to you sorry
