I have a 2009 mini cooper s the check engine light is on used the Schwaben scan tool check the engine lights.
When I checked the car I got codes PO120 and PO122. I then googled the symptons of these codes, this is what
I got______ The PO120 code puts the ECM in a failsafe mode>Which will cause various driving complaints. Example
lack of acceleration, high idle bucking or jerking, limited speed and possibly stalling. TPS sensor fault, the ECM detected
the output from the TPS sensor circuit (A) went outside of the specified voltage range in relation to TPS sensor circuit (B).

The TPS senor circuit (A) output to the ECM went below the specified voltage and is going to 2 volts or less.
The ECM controls fuel injection and timing to control engine speed. The car would be able to still be driven
very slowly with limited throttle response.

I'm experiencing the car with limited acceleration and no boost from the car itself, has anyone had this problem.

 

I'm still trying to search and gather more information concerning this problem with the car.

 

If you google "P0120 bmw" and "P0122 bmw" you will (I did) get lots of "hits".

Here's the link to one for the P0120 error code:

My "experience" (2nd/3rd hand at best) with the e-Gas system of other cars is there is no user serviceable parts in the system. With one car brand -- Porsche -- there was a recommended e-Gas calibration procedure to follow then afterwards check for any e-Gas error codes. If any present to replace the components the error codes indicated were the problem.
