P258F Torque Management Request Output Signal
The ECM/PCM produces a torque-management output signal for downstream consumers (TCM during shifts, hybrid module, transfer case) and detects a fault on this output — open, short, or feedback voltage outside expected range. Without it, downstream modules cannot synchronise their behaviour with the engine.
Is it safe to drive with P258F?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
