The P0302 code on your 2022 Ford Ranger signals repeated misfires in cylinder 2. The 2022 was the final year of the current-generation Ranger before the 2024 redesign, using the familiar 2.3L EcoBoost engine.
2022 Ranger Powertrain
The 2022 Ranger continues with the 2.3L EcoBoost 4-cylinder mated to a 10-speed automatic. This proven combination provides good power and efficiency for the mid-size truck segment.
Warranty Status
Your 2022 Ranger should still be under Ford's powertrain warranty (5 years/60,000 miles from in-service date). Check your coverage before proceeding with DIY repairs that might complicate warranty claims.
Common Misfire Causes
On the EcoBoost Ranger, typical P0302 causes include failing ignition coil on cylinder 2, worn spark plug, carbon deposits on intake valves (direct injection), fuel injector issues, and vacuum/boost leaks.
Diagnostic Strategy
The swap test remains most efficient—move cylinder 2's coil to another position and monitor for misfire migration. This identifies ignition failures without unnecessary parts replacement.
