The 2022 Ford Maverick offers two 4-cylinder powertrains—the 2.5L hybrid producing 191 combined horsepower or the 2.0L EcoBoost with 250 horsepower. Both configurations contain only 4 cylinders. When P0306: Cylinder 6 Misfire Detected appears, you're encountering an anomalous code.
Maverick's Efficient Powertrains
The first-year Maverick was designed from the start as a 4-cylinder compact truck. The standard hybrid and optional EcoBoost both use inline-4 architecture—no V6 was ever offered or planned. Cylinder 6 doesn't exist in any Maverick configuration.
Why This Erroneous Code Appears
Generic scanners expecting larger truck engines may generate incorrect codes. EcoBoost and hybrid diagnostic protocols can confuse some diagnostic tools. Aftermarket OBD devices may interfere with proper data transmission. ECU communication errors produce false cylinder-specific codes.
Proper Diagnostic Steps
Clear all codes and drive through various conditions—include hybrid-only mode if applicable. Use Ford IDS or professional equipment for accurate readings. Inspect the OBD-II port for damage. Remove aftermarket plug-in devices temporarily. Focus on legitimate misfire codes (P0301-P0304) that indicate actual 4-cylinder issues.
Compact Truck Considerations
The Maverick's efficient design achieves impressive fuel economy from 4-cylinder power. If actual drivability concerns exist, investigate valid diagnostic codes rather than chasing an impossible cylinder 6 misfire.
