'02 mustang 4.6L 02 sensor

[///m42 sport]

***Edit generic o2 Bosch sensor is #15736, OEM # is 13109****
The part # I swapped out is not correct.

So swapped my o2 sensor out today with a 2002 mustang bosch sensor. Its a 4 wire sensor which is what 318is's come with also.

spliced wires and heatshrinked them. Not sure if it mattered any but there are 2 white wires. Make sure you look at the orientation of the wires and connect the same whites.

Interesting to see if this makes a big diff in fuel economy.

Side note: this seems to have fixed my MPG gauge which was acting up lately. Good thing I didn't change out the cluster beforehand!!

Ok. So what is supposed to be the issue? Better fuel economy or more power? Please let me know. Thanks.

[///m42 sport]

umm, how about maintenance. This was to clarify the use of a generic bosch 4wire sensor instead of paying $$$$ for a 02 sensor from bmw.

[quinn11m20]

Oh! hmmm! Its just a cheaper o2 sensor. ok.

Just found this link today. writeup by bosch on splicing their O2 sensor

you have to watch if it's a bosch LSH6 or not. 318is stock uses LSH6 type sensors. However, the 2 white wires are for the sensor heating (a relay brings the 12V from battery so the orientation doesn't matter)
the black wire is for ground reference (which in some sensors is directly connected to the ground and in some others not
the grey wire is for the output which is a voltage between 0 and 1 volt created by the o2 flow over 300°C

[///m42 sport]

hmm, I wasnt sure where to check for the lsh6 when i did the swap. Everything is still running fine. Its been about a yr now.

link to the bosch site listing the generic o2 plug. So I got the wrong part :(

Bosch suggests (http://www.boschautoparts.com/VehiclePartFinder/Pages/VehiclePartFinderResults.aspx?MAKE=BMW&MODEL=318IS_&YEAR=1991&CAT=OxygenSensors) the following parts for e30 M42s:
13108 Oxygen Sensor - OE Type - Alternate Fit (Customer Choice)
13109 Oxygen Sensor - OE Type - Exact Fit
15736 Oxygen Sensor - OE SmartLink

$87.50 at ///m42 sport's link above. Seems like it's useful for any BMW, Mercedes, or VW from the early '90s onward.

For the $104.20 OEM part I'd be tempted to wire up a WBO2...they're only $200 (or $230 with a digital readout (http://www.diyautotune.com/catalog/-c-23.html)) and can be wired to send a standard O2 signal to the DME.

[///m42 sport]

Hey combine the wb02 with one of george graves gauges, and it'll look oem.

Those are cool! What a great idea!

I'd have used the check control panel myself, but he's really got a good thing going there.

OK... so just to be sure

I can walk into autozone/kragen and ask for a 2002 Mustang 4.6L o2 sensor

and this will be the part i need, then i can splice it up to my oem o2 sensor plug?

Sorry im lame at this kind of stuff

[///m42 sport]

check my corrections. The correct part # is stated at the top.

[thebutcher37]

so do i order this generic o2 Bosch sensor #15736 online or can i go into a local auto parts and ask for it?

sorry for the confusion, i just want to be sure, cause i keep reading about 3 wire and 4 wire sensors, and 1994 mustang, and the 2002 mustang which i now know is wrong now.. If you could in fact use a mustang sensor Im unsure about which one to ask for at the auto parts store.

[///m42 sport]

^yeah 15736. Idk what others are talking about, mine was 4 wire. and since theres alot of missinformation on web...thats why I got the wrong o2 sensor to begin with:mad:. I would rely on the bosch site for part #.

If you dont want to splice the wires then get the OEM O2 sensor with the adaptor already attached. Its just plug/play

However, my car has been running fine with what I installed and it was cheaper than the #15736. So that could be a alternative if you want a cheap "ghetto" swap.

[Balkanac]

Does anyone know how to test these? Im not sure if mine needs replacing, the car has done 168k kms (about 100k miles).

[thebutcher37]

Okay I just wanted to post up that I replaced my o2 sensor with ///m42 sport's accidental suggested 2002 mustang pre-cat o2 sensor #15716, Just to re-instate it is a 4 wire sensor grey,black, and 2-white, which I spliced into my existing oem plug picked up at autozone for $48 with CA taxes... Even though I am not passing smog it has been shown to do its job by lowering O2.. and my car seems to be running fine, just wish it would have been what made me pas smog.

[NO_CARRIER]

I don't get it... the Bosch website only has the original BMW sensor for $102 or a Universal for $87.50. It doesn't provide any part numbers for a Mustang o2 sensor.

Anyone know which o2 sensor / part number I require for a 1992 318i (north american) e36?:confused:

I want to make sure since most members on this forum seem to have e30's and apparenly the OEM BMW o2 sensor is a diff part number.

[locknload]

I just replaced my OE O2 sensor with a Bosch 15707 I bought from Amazon for $33, but you can get them from most parts places for about the same price. The reason I used this one instead of the ones recommended is, this is the same sensor, but the wiring pigtail is much longer, about the same length as the one I removed. I was hoping I could just disassemble the old BMW connector and re-use it on the new sensor, but the pins themselves are completely different. However, it still was a very simple matter to replace. First, I cut the connector off of the new sensor as close to the connector as I could. Then, I did the same thing with the old BMW connector, but with this one, I cut it a few inches away from the connector to give myself some room to solder. Then I just matched the colors of the wires and soldered and heat-shrinked them. This way, the wiring is all new and the solder joints are up near the connector, away from exhaust heat and road elements. Works great. The new sensor fits 88-89 Dodge D100, D150 and D250 pickups as well as '91-'92 Eagle Premier along with a few other Dodge products.
