Code P02FF: Propulsion System Inactive Timer Performance
Diagnostic & Technical Explanation
Code P02FF (Propulsion System Inactive Timer Performance) sets on hybrid/stop-start platforms when the monitor tracking how long the combustion engine remains inactive (off) during propulsion detects a value outside the expected performance window. Causes are a hybrid battery/traction system fault forcing unexpected engine restarts, a stuck starter/ISG, or a miscalibrated stop-start control module.

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.
