Is your idle speed OK? Usually a bad air flow sensor position indicator will affect your idle speed. (high idle) What about your fuel economy?

If your car is running fine, retrieve the code again, then erase it by pressing the button 6-8 seconds. See if the trouble code pops up again after driving your car. If so test or replace the part.

Good luck and welcome to the board! :p
