Investigating P0100 on Your 2022 Ford Maverick
A P0100 code on your 2022 Ford Maverick means the PCM has detected a malfunction in the mass air flow (MAF) sensor circuit. As the first year of the Maverick, your 2022 model uses either the 2.5L hybrid (standard) or the 2.0L EcoBoost (optional), both relying on the MAF sensor for fuel control.
Symptoms
- Check engine light on
- Rough or unstable idle
- Hesitation during acceleration
- Reduced power
- Poor fuel economy—especially disappointing on the fuel-efficient hybrid
- Possible stalling
Common Causes
- Contaminated MAF sensor (34%) — Oil, dirt, or debris after three-plus years.
- Wiring or connector issues (22%) — Heat and vibration.
- Faulty MAF sensor (18%) — Internal failure or first-year defect.
- Intake or intercooler piping leak (13%) — EcoBoost turbo piping on the 2.0L. The hybrid's simpler intake is less prone.
- Air filter restriction (8%) — Overdue change.
- PCM issue (5%) — Possible on first-year model.
Diagnostic Steps
- MAF sensor cleaning — Remove and clean with dedicated MAF cleaner spray.
- Intake inspection — Check turbo piping on EcoBoost models.
- Connector inspection — Check for corrosion or looseness.
- Air filter check — Replace if dirty.
- Scan tool data — Verify MAF readings.
- MAF replacement — If cleaning doesn't resolve it.
Repair Costs
- MAF cleaning: $10–$15 (DIY)
- Air filter: $15–$25 (DIY)
- MAF sensor: $125–$300
- Intake boot/piping: $75–$200
- Wiring repair: $85–$260
Warranty
Your 2022 Maverick's 3-year/36,000-mile warranty extends through 2025. The federal emissions warranty covers the MAF sensor for 8 years/80,000 miles through 2030.
