Hey guys the Mini threw a CEL today. The code comes up as P112B and says error in air/fuel metering. I have been trying to find more information but as far as I can see that code doesn't even exist. Any ideas?

 

It looks like a Mini specific code since it starts with 1 after the letter P. If it was 0 it would b generic.

 

I think the code has to do with your MINI's Pedal or Throttle position B.

 

i had this one also, if i remember correctly it was the maf sensor. my maf wasnt failing it was the unichip. i solved the harness problem and bye bye cel

 

Thanks guys. Can anyone confirm wether it is throttle position or maf?

 

mine also just threw this code yesturday. Autozone said it was possibly the Front o2 sensor cab anybody confirm this?

 

Count me in on this one too... My MINI threw the code yesterday after installing the Alta CAI this past weekend - related?

I reset and have had no problems since... in two whole drives... will update if it returns

 

I've figure this out!!!! The P112B comes up air fuel ratio... there was a bulletin put out by mini. This actually has something to do with the thermostat. Just take it to your local dealer they have to do a re-flash.

Just had mine done today by the new Mini Monmouth!!!

 

Guys I hate to bring up a dead horse but has anyone else dealt with this and come to a definitive conclusion on it? My '07 Coop S with 47k miles on it through this code today. Car runs/drives fine just has the yellow CEL on.

If it was just a reflash, How much did they charge you to reflash it? And if it was an o2 sensor or MAF problem....how did a reflash correct it?

Any help is greatly appreciated...and again, sorry for bringing up such an old thread.

 

If I remember correctly this ended up being a throttle position sensor for me. There are two of these sensors so the car will continue to operate correctly but one will need to get replaced.

 

Oddly enough.... My CEL didn't come on this morning. Drove 45 miles to work car continued to drive as normal and the light never came on....? Any ideas how/why it reset itself?
