Troubleshooting the P0100 Code on an F350: Diagnosing Air Intake Sensor and More

Hi, everybody. I got a voice over this part because TikTok keeps taking the sound away, even though that’s their sound. I don’t know why, but we’re working on F350 with the P0100 code that we’re going to diagnose. Cuz the owner already change the mass airflow and still the code is active. You can see that’s usually the problem, but that’s not the case. And now my regular sound kicks on now. So now we gotta start probing. We’re gonna go check the air intake temperature sensor, 5 volt reference. We’re gonna check the mass airflow reference, and we’re gonna check ignition voltage.
