First off thanks for the good information. I had this issue and replacing the MAF fixed it, however I recently had this happen again after 600 miles or so. When I shut off the car after the warning the car starts right up and runs a few minutes. But after 10 minutes or so it gives me the P3190 error. Just checked and the MAF is clean as a whistle, is it possible my screws on the MAF were not tight enough? They were tight but probably not as tight as they could have been. Thanks in advanced. 2009 prius, 181k miles.
