Propulsion System Inactive Timer
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.
These 1 diagnostic trouble codes share one
detection mechanism and one repair path, which is why MechanicDB groups them into a single
authored fault family rather than repeating the same explanation 1 times.
