Code P0297 Ford Description

The P0297 code for Ford vehicles indicates a Vehicle Over-Speed Condition, which typically occurs when the vehicle's Engine Control Module (ECM) detects that the vehicle is traveling at a speed higher than the predetermined limit. This code is usually triggered when the vehicle is being driven at excessive speeds, which can pose a safety hazard and potentially cause damage to the engine or other components. The ECM monitors vehicle speed using various sensors, such as the vehicle speed sensor (VSS), and compares it to the manufacturer's specified limit to determine if the vehicle is over-speeding.
