P0297 OBD-II: Vehicle Overspeed Condition
P0297 Severity
Will P0297 go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P0297?
The Vehicle Speed Sensor tells the engine control module (PCM) how fast the vehicle is going. If the vehicle is driven over a certain speed, it will set code P0297.The PCM may put the vehicle into "limp home mode" to limit the speed that the vehicle can be driven. Repeated setting of this code may void your warranty.
