If your state/county has emissions inspection that relies on the OBDII and dyno method read this. My car has a faulty TCC and it throws the P0741 code. You will fail inspection if your car has any PCM codes. The way to combat this without having your car repaired (very expensive) is as follows. First, through the DIC, clear the codes. Do not go to inspection at this time as your emissions system will not be able to be read by the inspectors computer and you will fail. Drive the car for a week or two only in third gear. The P0741 only sets if yoiu are in overdrive and get above 41 mph. After your week or so of driving your systems will be "ready". Go back to inspection, and you should be golden. I checked for the code after every drive and it never appeared.
