Did you find an answer Jimshorts? I just got this code in my 07 335i and would love to know what to do about it. Everything I've read is either a debate between an O2 sensor (location?) or this below. Any ideas would be appreciated.
P112F - Manifold Absolute Pressure to Throttle Angle - Too High (Bank 1)
The fault is recognized when the relationship between the indicated intake manifold pressure and the mass airflow calculated based on throttle-valve angle is not correct
Potential problem source(s): - Measured value for intake manifold pressure (absolute) too high
- Vacuum leak within induction tract/crankcase
- Incorrect throttle-valve angle
- Pressure sensor defective
- Check intake system and crankcase for leakage
- Check throttle valve (contamination, carbon deposits, icing)
- Check plug and wiring harness between intake- manifold pressure sensor and DME
- Check plug, wiring harness at electric throttle- valve actuator
- Replace pressure sensor
- Replace throttle valve

So if its an O2 sensor I know what to do about it, if its a vacuum leak or throttle valve issue I'm kind've at a loss.
Also I'm seeing if it was just bad gas that threw the code. The car had some old gas in it and hopefully it just burned incorrectly and should clear up after the next tank gets through. I'll keep you posted.
