SAE Standard (Generic)
Family: Engine Overspeed Condition
Code P0297: Vehicle Overspeed Condition
Diagnostic & Technical Explanation
Code P0297 (Vehicle Overspeed Condition) sets when engine RPM or vehicle speed exceeds the calibrated safe limit, most often from an aggressive downshift, a slipping clutch/torque converter allowing engine flare, or a stuck throttle. This is a real mechanical event flag rather than a sensor circuit fault.

This is the first procedure in the authored
consideration order, not a measured cause likelihood. Execute it only when its prerequisites
and diagnostic findings support it. Its cost and labor estimates (where known), the step-by-step procedure and the
remaining 2 procedure(s) are in the licensed dataset. Ordering context.
