This addressed an "EGR insufficient air flow" P0401 engine code error for a 2008 Ford F150 v8. After more than a month there has been no repeat of the P0401 code. P0401 error can also be caused by excessive buildup in throttle body assembly but in this case the issue was the EGR sensor. This part did the trick at a very reasonable price compared to the in-town auto parts stores.
