AvatarByCarl Frisch

Ford F150 Code P0306 is an error code that indicates a misfire in the engine’s number 6 cylinder. This is one of the most common trouble codes for vehicles equipped with the Ford F150’s 4.6L V8 engine. The code is triggered when the powertrain control module (PCM) detects an abnormally low level of compression or an incorrect fuel to air ratio in this cylinder. When this happens, the PCM will turn on the Check Engine Light and store a P0306 trouble code in its memory. In addition, you may experience other symptoms such as poor fuel economy, engine misfires, stalling and rough idling. Diagnosing and repairing this problem should be done as soon as possible to prevent further damage to your vehicle.
