What P0174 Means on Your 2024 Ford Maverick
The P0174 code on your 2024 Ford Maverick signals that Bank 2 of the engine is running too lean. The 2024 Maverick continues to offer the 2.5L hybrid as standard and the 2.0L EcoBoost turbocharged 4-cylinder as the optional performance engine. P0174 most commonly affects the 2.0L EcoBoost due to its turbocharged system. A lean condition means the engine is receiving more air than the optimal amount relative to fuel.
Common Symptoms

- Reduced acceleration response
- Lower fuel economy
- Hesitation when pressing the gas
- Possible boost-related whistling sound
