The P0302 code on your 2021 Ford Bronco Sport indicates the PCM detected misfires in cylinder 2. The compact SUV offers two EcoBoost engine options with different cylinder configurations.
Bronco Sport Engine Options
The 2021 Bronco Sport offered the 1.5L EcoBoost 3-cylinder (base) and 2.0L EcoBoost 4-cylinder (Badlands and First Edition). On the 3-cylinder, cylinder 2 is the middle position. On the 4-cylinder, it's the second from front.
3-Cylinder Engine Considerations
The 1.5L 3-cylinder is a modern turbocharged engine but has only three cylinders. A misfire in any cylinder is more noticeable with fewer cylinders to compensate. Proper diagnosis is important.
Warranty Status
Your 2021 Bronco Sport should still be under Ford's powertrain warranty. Verify coverage before DIY repairs that might complicate warranty claims.
Diagnostic Approach
The coil swap test works on both engines. Move the cylinder 2 coil to another position and see if the misfire follows. This identifies ignition coil failures efficiently.
