P02FF Propulsion System Inactive Timer Performance
The timer that monitors how long the propulsion system has been inactive (used by hybrid and stop-start strategies to schedule rebalancing tasks) is not behaving plausibly — typically a clock or PCM-state fault.
Is it safe to drive with P02FF?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
