     Any loss or corruption of signal from a wheel speed sensor will affect engine and trans performance. There is no silver bullet answer for a fix to the symptoms you are asking about. Pull the codes , Check TSBs , Google forums for pattern failure things to look for, follow the diagnostic steps in repair software or repair manual. Good Luck

              You might be better served by posting issue on maxi-fix instead of this forum. I got to believe there's other codes in other modules besides PCM. Their might just be in ABS or other module some informational code telling you that your disabled and you need to fix that first (default strategy). P0171 is just for fuel trim exceeded,P0533 for AC pressure transducer signal which possibly share 5 volts with something and P0014 is for exhaust camshaft position not what expected look at actual vs. desired on scanner you'd know if that's active because of reduced power message.
