Q: What does code P0297 mean?

Vehicle Overspeed Condition. P0297 is a generic powertrain code that indicates the engine control module (ECM) has detected a vehicle overspeed condition, meaning the vehicle's speed exceeded a manufacturer-defined maximum threshold for a sustained period. The ECM typically monitors vehicle speed via the speed sensor or calculated from wheel speed sensors, and sets this code when the speed signal indicates an overspeed event that is not plausible under normal driving conditions.
