In Reply to: HELP! NEW O2 and still DME 1222 & constant EML. posted by Jim on December 17, 2000 at 22:41:46:

Cleaned the crank sensor, retried resetting the DME and this time the PEAK reset unit and the DME flash codes match.....NO FAULTS.
Now for the EML dilemma.
Chatted with my CCA Tech wizard and he suspects faulty SII board. He suspects leaky battery has taken out circuits causing tach to act up and illuminate the EML.
As for traction control I'm not sure. It's an automatic that originated in Colorado Springs.
When I pulled the cover where the EML connector is supposed to be I found nada.
Took it out for fresh fuel and on the way home decided to see how much difference this new O2 sensor would make. Much to my surprise it kicked down and shot off beautifully. Did have a few stutters going into town but I attribute that to sitting without being driven regularly.
Except for the tach sticking at 3k it really hopped up quick and finally has it's kick back in the throttle.
Now to solve the EML & tach issue, then slap on some more wax, slip in the new Confortti and Dinan chipset and my wife will be set for some time.

Thanks for the input Bill.



Ya know I really love BMW's.......except when I can't figure them out.
Last month after getting car back from paint shop I started getting intermittent EML lamp. Disconnected battery and lamp would vanish for a time. Now it stays ON all the time, even with key off & out of car. Only disconnecting batt will kill it.

Then car started running & idling like crap.
Checked DME codes and found 1222, which Bonneville lists as Lambda #1, which some have translated as faulty O2 sensor, others say it means rich/lean mixture and O2 is actually 1221. So I disconnected O2 connector and engine came to life. Hummed beautiful and dramatically responsive.
So I changed out O2 w/ new one (what a Engineering masterpiece of Sh-- design this is!!)and also found bad vacuum line from intake to bellows, which I replaced. Thought this might be cause of EML. Pulled filter box, checked bellows for cracks, etc. and then started.
Idled much better with better response. I tested AFM w/ slight touch and it caused rpm to stumble, which is supposed to be normal.
Checked DME and 1222 is still there w/ EML lamp brightly lit!?!?!?!

So now I'm going try some other tips found in the archives.
First, clean and gap crank sensor.
Second, install new Bosch silvers, distributor cap & rotor. Third re-fuel tank with fresher 93 and a can of MolyLube injector cleaner.
Lastly, if all this fails I'll pull the AFM and try a trick I found that requires opening the AFM and tweaking the air/fuel screws.

I found mention of an EGO sensor. Can anyone tell me what this is specifically? I'm betting it another damn emissions type piece of crap. It's an outside guess at this point.
I'm running out of ideas and have exhausted the archives.

Any other known tips or suggestions are appreciated.

Jim
