In the previous video, I looked at ways to test the Maf sensor on my 2006 f150 with a 5.4 3v motor. These tests deal with the wiring harness and looking for a short to ground. A short to ground in most cases would result in a wire rubbing though. this happening will also contribute to a P0102 and a P0104. Ideally you want to test every pinout back to the ecm plug but that can be done also during the first test to pinpoint any problems.

So your saying it is better to test your sensors than to just replace them all and hope that solves your problem?😂🤣😂🤣

That's correct people must troubleshoot before changing parts
