The P0302 code on your 2022 Ford Explorer signals repeated misfires in cylinder 2. The 6th generation Explorer uses EcoBoost power, requiring consideration of both traditional misfire causes and turbo-specific issues.
2022 Explorer Engine Layout
The 2022 Explorer offers the 2.3L EcoBoost 4-cylinder (rear-wheel drive) and 3.0L EcoBoost V6 (ST and Platinum). On the 2.3L, cylinders are numbered 1-2-3-4 front to rear. On the 3.0L V6, cylinders 1-3 are on one bank and 4-6 on the other with 2 between them.
EcoBoost Misfire Sources
Common P0302 causes on EcoBoost Explorers include ignition coil failure, spark plug issues (more critical on turbocharged engines), carbon buildup on intake valves, fuel injector problems, and vacuum/boost leaks.
Diagnosis Strategy
Start with the ignition coil swap test—it's the most efficient way to identify a bad coil. The Explorer's engine bay provides reasonable access to ignition components. Check warranty status first, as 2022 models may still qualify for powertrain coverage.
Warranty Status
The 2022 Explorer should still be under the 5-year/60,000-mile powertrain warranty if under mileage. Verify coverage before DIY repairs that might complicate warranty claims.
