A P0303 code on your 2023 Ford Bronco indicates that the engine control module has detected cylinder 3 misfires beyond acceptable parameters. This capable off-roader's EcoBoost engines require proper diagnostic attention.
2023 Bronco Powertrain Options
The 2023 Ford Bronco continues with the 2.3L EcoBoost four-cylinder (300 hp) and 2.7L EcoBoost twin-turbo V6 (330 hp). Raptor models use a more powerful version of the twin-turbo V6.
EcoBoost Technology
Both engines combine turbocharging with direct injection. Boost system integrity is essential for proper combustion. Off-road conditions can stress boost system components.
Four-Cylinder Configuration
The 2.3L has four cylinders, each contributing 25% of power. Cylinder 3 misfires create noticeable rough running, especially at idle.
Twin-Turbo V6
The 2.7L uses two turbochargers for balanced power delivery. Cylinder 3 on one bank requires attention to bank-specific boost and fuel delivery.
Off-Road Capability
The Bronco excels in challenging terrain. Ensure proper engine function before tackling difficult trails.
