What Does P0100 Mean on Your 2024 Ford F-150?
A P0100 code on your 2024 Ford F-150 indicates the PCM has detected a malfunction in the mass air flow (MAF) sensor circuit. This is uncommon on a new truck and likely points to a factory issue or contamination.
Your 14th-generation F-150 offers multiple engine options—2.7L EcoBoost V6, 3.5L EcoBoost V6, 3.3L V6, 5.0L V8, or 3.5L PowerBoost hybrid—all relying on the MAF sensor for accurate fuel delivery.
Symptoms
- Check engine light on
- Rough or unstable idle
- Hesitation during acceleration
- Reduced power—noticeable when towing
- Poor fuel economy
- Possible stalling
