How TO: CEL/MIL Eliminator!

[Kansei]

*bump* can anyone verify these colors? http://www.msprotege.com/forum/showpost.php?p=2442223&postcount=44

it's from a picture I found online, but it isn't a generic picture because it does show the factory plug.

this is what I should do cuz now I have my AWR header right?

I checked mine and drew this up really quick. I hope it makes sense.

Thanks for the image, I think that's how I have it wired. I've started the car 5 or 6 times and have driven maybe 45 minutes and the CEL isn't bad yet so I think things are ok.

Im getting prepped to do a header install, Im doing the following:

Heat wrapping the Headers
Installing the Headers
wirring up the Cel Eliminator

Im needing help in all 3 as its a first timer for me.

Im going to muster up a page with pics and details of all 3 to help out as the "How To's" We have now are only for the Cel Eliminator and it lacks pics of what thing look like (Good diagram though A+)

My Question for the Cel eliminator at this point is what couler stripes and in what order are the stripes on the 1m ohm resistor?

I got a variaty pack (only pack they had with a 1m ohm)

IS IT Brown - Black - Green - ?

Im going to have a few more questions Im sure, Ill provide pics of each step I go though making sure Im on the right path, That should be some time next week. Thanks!!!

Step1:
-Pop Open the Hood and get a look at the 2nd Oxygen Sensor
-There is a clip..Push the clip in and pull out the Male-Female Connection
-Using Adjustable Wrench Remove the Oxygen Sensor

DAMIT, Now Im confused!!!!

Okay, so If I pop open the Hood and look at the o2 sensor, is this not the FIRST o2 sensor, and NOT the Second?

Isnt the Second o2 Sensor UNDER THE car?

From top to Bottom

EGR (Visible when the hoods up)

First o2 Sensor (Visible when the hoods up)

Second o2 sensor (Visible from Under the car)

Also the Pics in this "How To" show under the hood, but we see the First o2 sensor dont we???

If you open the hood and look down you can see both sensors the second one is down not to far after the pre cat on the pass side. Both connectors for both sensors are side by side almost.

Gotcha, and thanks, I just realized the pic show the Clip to disconect, and you still need to be under the car to get at the sensor non the less.

 

[Laser03pro]

Yeh you still need to be under the car you can see both the wires here. Wire on the bottom goes to the second 02 sensor.

 

[Rac3rX]

For the wiring, I searched and so far Brown - Black - Green resistors are the 1m ohm.

As to the diagram, I cut the blue wire & soder one end of the resistor, one end of the capacitor & one end of the bleu cut wire all together & The other side of the blue cut wire gets sodered to the un-sodered end of the resistor.

I tape up all this leaving the un-sodered end of the capacitator exposed, and I then expose some of the white wire (without cutting it) and soder in the exposed end of the capascitor, taping it all up when done.

So far have I made a mistake?????


Thanks For any help!!!!

would this mod works if the 2nd sensor is not plugged in?
since i got a ractive header that only take the 1st sensor and no where else to put the 2nd one...

You need a bung drilled before the second cat for the sesor to go into and it need be plugged in.

The Cell comes from the 2nd o2 Sensor & the fix is applyed to it.

eep no. If you are going to get a bung drilled, get it drilled AFTER the second cat, and then install your 2nd O2 sensor there and you won't need. the CEL/MIL eliminator. That's why I got the MAM high-flow cat midpipe as it has a bung after the cat (it's probably there for people with widebands but works fine for my 2nd O2 sensor.

That is a even better solution, you can extend the o2 sensor behind the second cat, THEN you dont actually need the fix.

However INORDER for this fix (Mil Eliminator) to work I am correct!

So its not "eep no" Its Better yet. (ughdance)

 

[Kansei]

Yeah I guess the "eep no" wasn't appropriate, I just wanted to let him know that if he was going to get a bung welded anyway, might as well toss it after the cat; then just extend 4 wires and be done with it. Actually the MIL eliminator is probably easier because routing the wiring back to the rear sensor location was sorta a pain.

update....after about 2 yrs I through a CEL. I have a faulty rear O2 and will replace it....and yes I have the non-fouler mod

Replace it with my setup. MUCH cheaper and easier to do again if something goes wrong down the road.

no thanks...I prefer to keep the 02 in working order withour modifying the signal to the ECU, that way I know if the primary O2 is working or if anything else on my emissions system is fried.

If I'm not mistaken, your setup is telling the ECU that all is good when in fact it might not be. You ECU is getting a "cheated" reading from the O2 becaus the MIL fix is limiting the voltage readings. With the non-fouler trick, the ECU still reads whatever signal the O2 sends to it.

I'll keep y'all updated

No, my setup tells the ECU that the second O2 is there and working fine. The second O2 is for emissions only, so the end result is exactly the same as the non-fouler. The non-fouler is sending the ECU and innacurate signal. If it sent the correct signal, the ECU would throw a code because it's reading outside of the normal emission range. It's two means to the same end, except mine is easier and cheaper to replace if something goes wrong. Plus it's not in the exhaust flow, so there is less restriction.
