The 2022 Lincoln Nautilus offers two engine options: a 2.0-liter turbocharged 4-cylinder producing 250 horsepower and a 2.7-liter turbocharged V6 delivering 335 horsepower. Only the V6 configuration includes cylinder 5 as a legitimate position. A P0305 diagnostic trouble code requires verification of your specific engine type.
Understanding P0305 by Engine
On Nautilus models with the 2.7L twin-turbo V6, P0305 indicating "Cylinder 5 Misfire Detected" is a valid code requiring traditional misfire diagnosis. On 4-cylinder models, P0305 would be anomalous since only cylinders 1-4 exist.
V6 Engine Configuration
The 2.7L EcoBoost V6 uses twin turbochargers for strong performance. Cylinder 5 is positioned on the driver's side bank. The turbocharged design places premium demands on ignition components.
4-Cylinder Consideration
If your Nautilus has the 2.0L turbo-4, a P0305 code is anomalous and indicates a diagnostic system issue rather than an actual cylinder 5 problem.
Model Verification
Verify your engine type before proceeding. V6 models typically have different trim or package designations.
