P0297
Vehicle Overspeed Condition
- Severity
- Low
- Driving
- Drivable — book it in
The vehicle has been driven faster than a limit set in the module. This is not an engine fault. Speed limiters are fitted for all sorts of reasons - a manufacturer limit, a speed-rated tyre restriction, a fleet or insurance setting, or a limit tied to a particular tyre or wheel specification.
Possible causes
- CommonVehicle driven above its programmed limit
- PossibleLimiter set for tyres of a lower speed rating than those fitted
- PossibleFleet, insurance or telematics limit configured in the module
- PossibleWrong tyre or wheel size making the module read speed incorrectly
- PossibleFaulty speed sensor recording a false reading
What you might notice
- Recorded after a period of high-speed driving
- Check engine light on
- Sometimes an audible warning at the limit
- No effect on how the car drives
What to check, in order
- Check the speed rating of the tyres actually fitted. A limiter set for winter or space-saver tyres will trigger long before the car's own maximum.
- Check whether a non-standard wheel or tyre size has been fitted, which makes the module calculate speed wrongly.
- Check for a fleet, insurance or telematics limiter configured in the vehicle.
- If the speed recorded is implausible, suspect a speed sensor fault rather than the driving.
- Clear the code and see whether it returns in normal driving.
