replacement O2 sensor

anyone know of a aftermarrket 02 sensor for the '02 K1200LTC? 186 + shipping (for faster shipping) is kind of steep!

Count the wires, it is probably either 3 or 4, and get a matching Bosch Universal one with the same number of wires. The newer Bosch universal O2 sensors come with waterproof splicing connectors, you just cut the existing sensor wire and splice the new one in.

Check with your local auto parts suppliers for them.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Thanks, I do want a new 02 Sensor though. It's time with 116k miles on it.

Yep, that is the Bosch Universal Splice in I was talking about. Good price too! No need to look further.

Thanks David do you happen to know the resistance compared to the voltage range on the sensor on these, heck it;s been so long since I have fooled with this stuff I forget the common values

shoot i completlyhhosed up what i meant to type (brain doesn;t seem to get the finger to do what I meant them to do sometimes <g>)

Anyhow what I meant
do you know the resistance value of the 02 sensors? do you know what the voltage rise should be at what temp, i can;t find anything on them any where like back in the old days <g>

I never checked one. Just replaced them when the ECU codes say they are needed. Replaced the one on my 525i about 6 months ago, and recently had to replace the two "Pre-Cat" ones on the 740iL. That car still has two more "After-Cat" ones, but they are not giving me codes yet.

Question: I have not heard of anyone with an LT ever replacing the O2 sensor. Why do you feel you need to?

O2 Sensor

I replaced mine after 100k because the info on the Robert Bosch site said in effect 100k was all she wrote. Total waste of time and money, IMHO, because it made no difference in running and/or fuel economy. So once again, David is correct.

just to let you know, your sensor could have been bad and you never know it, the computer will make up the difference in a slightly degraded 02 sensor. not saying yoru was bad but without knowing the values and actuually testing it there is no way to say good or bad

Question: I have not heard of anyone with an LT ever replacing the O2 sensor. Why do you feel you need to?
just because of years doing drivability, 02 sensors are known to break down over time, heck it used to be very common to replace them about every 30k miles, but most won't know it unless they actually test the 02 sensor by heating them to certain degrees and reading the voltage output at various temps, or finding no continuity in them.

I forget the temps vs voltage readings anymore though, and I gave most all my books away after my accident. 02 sensors actually work off exhaust temps. Most techs only replace items when they completely fail and they store a code, 115k miles I'm sure it is pretty well done especially knowing how rich these lt's run at or under hard throttle, which is also known to cause premature failure of 02 sensors, I have to pull my exhaust and have it welded so while i got it off this is the time to replace it

take a new one heat it and read the voltage increases, but you have to know which wires are what on them to do that.

A direct replacement from Bosch is part number 0 258 003 475

It can also be found using number C5010-61265.

I did a quick search on the net and found one for $113.00 immediately and I am sure it can be had for much less at other places. This is a direct plug-in style and no soldering or anything is needed. I bought mine from Mercedes, so no need to go to BMW. Any place carrying Bosch should be able to supply it.


I have attached a document I wrote when I replaced my O2 sensor, which gives additional information.

Stephan,
In your document you mentioned poor gas mileage. Has your sensor replacement had any effect on MPG?
TIA

I don't have the exact numbers in front of me, but it went back in to the low 40's immediately. Of course the bike ran better overall as well and the smoke was reduced significantly.

I also added the new NGK Iridium plugs at the same time. Not that it created another 15 HP and gained 25 MPG, but joking apart, it seems as if the engine runs "smoother". Especially at idle or lower rpm's.

Talking O2 sensor for 05

Does anyone know the Bosch part number for the 05 O2 sensor. Has a different part number than pre 05 at the dealer.

Exclamation Re: replacement O2 sensor

Bump

I was doing a search to gather information on replacing my 02 sensor and came across this thread. The person that gave the information on the part may not be an active member any more since his last post was in 2006. Just want to get some input from others. The part number that is list is for a plug in replacement, no splicing required.

Did a quick Google search on the second part #C5010-61265 and found several hits... this one was the first and available for $92...
