The P0302 code on your 2021 Ford Bronco indicates the PCM detected misfires in cylinder 2. The reborn Bronco offers two EcoBoost engine options, both turbocharged and requiring specific diagnostic considerations.
2021 Bronco Engine Options
The 2021 Bronco offered the 2.3L EcoBoost 4-cylinder (base) and 2.7L EcoBoost V6 (optional). The 2.3L has cylinders 1-4 front to rear, while the 2.7L V6 has different bank configurations.
EcoBoost Misfire Causes
Both Bronco engines share EcoBoost technology considerations—direct injection can cause carbon buildup over time, turbo boost affects cylinder pressure sensitivity, and ignition components must be in good condition for optimal turbocharged operation.
Off-Road Considerations
Broncos often see off-road use. Water crossing, dust, and debris can affect ignition system components. After off-road adventures, check for moisture intrusion in coil connectors if misfires develop.
Warranty Coverage
The 2021 Bronco should still be under Ford's powertrain warranty (5 years/60,000 miles). Engine misfire issues are covered unless caused by owner abuse or modifications.
