What Does P0100 Mean on Your 2024 Ford Explorer?
A P0100 code on your 2024 Ford Explorer indicates the PCM has detected a malfunction in the mass air flow (MAF) sensor circuit. This is uncommon on a new vehicle and likely points to a factory issue or contamination.
Your 6th-generation Explorer is available with the 2.3L EcoBoost four-cylinder, 3.0L EcoBoost V6 (ST and Platinum), or 3.3L hybrid powertrain. All rely on accurate MAF readings for fuel delivery.
