What Does P0172 Mean on Your 2024 Ford F-150?
The 2024 Ford F-150 offers multiple engine options: a 3.5L EcoBoost twin-turbo V6 (400 hp), a 5.0L Coyote V8 (400 hp), a 2.7L EcoBoost V6 (325 hp), and a 3.5L PowerBoost hybrid V6 (430 hp). P0172 means the PCM detected a rich condition on Bank 1. On the V6 engines, Bank 1 is one of the two cylinder banks. On the V8, Bank 1 is the passenger side.
On a brand-new 2024, this code should be covered under Ford's factory warranty.

Top Causes of P0172 on the 2024 F-150
- MAF Sensor Issue (30% likelihood): The F-150's MAF sensor can have factory defects or pick up early contamination, especially on turbo models with PCV oil vapor.
- PCM Software Calibration (30% likelihood): Ford may have released a software update for fuel trim optimization on the 2024 F-150.
- Faulty O2 Sensor (20% likelihood): A defective upstream O2 sensor can cause incorrect fuel trim feedback to the PCM.
- Boost or Intake Leak (20% likelihood): On EcoBoost models, loose charge piping or intercooler connections from assembly can allow unmetered air.
How to Diagnose P0172 on Your 2024 F-150
- Take it to the Ford dealer. The 2024 F-150 is covered by Ford's 3-year/36,000-mile bumper-to-bumper and 5-year/60,000-mile powertrain warranty.
- Ask about TSBs. Ford frequently issues bulletins for engine management on F-150s.
- Check the air filter. Ensure proper installation.
