The P0302 code on your 2022 Ford F-150 signals that the PCM detected repeated misfires in cylinder 2. Whether you have the EcoBoost V6 or 5.0L V8, systematic diagnosis identifies the faulty component.
Engine-Specific Cylinder 2 Location
On the 3.5L and 2.7L EcoBoost engines, cylinder 2 is on the rear bank. On the 5.0L V8, cylinder 2 is on the passenger side bank. Locate your specific engine's cylinder layout in the owner's manual or service information.
Common P0302 Causes by Engine
EcoBoost engines commonly experience misfires from carbon-fouled intake valves (direct injection), failing ignition coils, and spark plug issues. The 5.0L V8 typically suffers from traditional ignition failures—coils and plugs being most common.
The Coil Swap Test
Both engine types use coil-on-plug ignition allowing easy swap testing. Move the cylinder 2 coil to another cylinder, clear codes, and test drive. If the misfire moves, you've found the bad coil.
EcoBoost Carbon Buildup
Direct injection EcoBoost engines don't wash intake valves with fuel. Carbon deposits can build up and affect air flow. If ignition and fuel components check out, consider intake valve inspection and cleaning.
