A P0303 code on your 2020 Ford Ranger indicates that the engine control module has detected cylinder 3 misfires beyond acceptable parameters. This midsize truck features Ford's capable EcoBoost powertrain.
2020 Ranger Powertrain
The 2020 Ford Ranger uses a 2.3L EcoBoost turbocharged four-cylinder producing 270 horsepower. This efficient engine provides strong torque for truck duties.
EcoBoost Four-Cylinder
The turbocharged engine combines boost pressure with direct injection. With four cylinders, each contributes 25% of power. Cylinder 3 misfires significantly affect smooth operation.
Turbo System Integrity
The turbocharger increases engine output through pressurized air. Boost leaks or wastegate issues can create lean conditions affecting specific cylinders.
Truck Usage Considerations
Rangers handle towing and work duties. Misfires under load indicate potentially more serious issues than idle-only misfires. Document when symptoms occur.
Ford Quality
The Ranger has proven reliable since its 2019 return to the US market. Address misfires to maintain dependable truck operation.
